It is applied to a substrate (such as a metal sheet) and then printed with a color pattern on the luminescent ink using a color halftone dot printing technique to display its vivid color and luminous effects. [Previous technology] Objects that can shine in the dark have always attracted people's attention since ancient times. With the rapid development of today's technology and the deepening of optical research, related luminescent materials and technologies are becoming more mature and widely used. Luminescent materials have evolved from general electroluminescent, display and illumination materials to materials that are excited by high-energy rays, cathode ray, light, sound, heat, and chemical, biological, and mechanical energy. They are widely used in ultra-thin TVs, liquid crystal displays, and Key materials in high-tech fields such as precision sensors (such as the reference [1]) are used in every corner of people's lives, and the long-lasting luminescent materials are also one of the recently developed luminescent materials. Long-lasting luminescent material 疋 a photoluminescent material that absorbs and stores excitation energy through the irradiation of light. After stopping the excitation, the stored energy can be gradually and continuously emitted in the form of visible light for several hours or even For several tens of hours, it is a light-storing luminescent material. The new long-lasting luminescent materials are more non-toxic, non-radioactive, bright, and have a long luminescence time (such as reference [2]), which is extremely environmentally friendly. Therefore, Changyuhui luminescent materials are widely used in: electronic appliances, commercial places, civil facilities, military facilities, rescue equipment, arts and crafts, communications, electricity, petroleum, chemical, textile, construction, building materials, mining, machinery, public security, fire protection. , transportation, 5 aviation, post and telecommunications, hospitals, tourism, 'combined fields (such as reference [3]). The application of iron plate products is quite extensive, such as indicator total, wide can, iron gift box, vehicle exhaust pipe, etc. The present inventors attempted to formulate a luminescent ink and an iron piece by formulating a mixture of materials and (4) oil (four), and the film exhibits the effect of a luminous color to increase the strength of the iron piece product, commerciality and even Anti-counterfeiting effect or military use.

Ll、： 仪光產品的原料相同。不同的是本發明專注 的研究㈣於彩色印刷，也就是不止要求良好的夜光， =須顯不彩色網印的圖形效果。目前有關夜光產品的開發以美 -日本以及大1¾為全世界的重鎮。本發明的產品較目前市面 上既有的夜光產品有明確的優勢，將會對夜光產品的應用帶來 更為廣泛的空間。 • k著長餘禪發光材料研究的日益深入，所發展出材料的亮 度與品質也有很大的進步。然而長餘哗發光材料並不能作為最 終產品，必須與其他材料配合加工再製造才能應用於日常生活 中。因此近年來，許多相關應用技術也逐漸發展出來。 目前在夜光印刷方面，既有的產品似乎集中在簡易的標示 牌β製程就是先將圖案印上，再將長餘暉微米粒子攙入透明漆 t並印在基材上的淺色部份區域，將其當成色彩與夜光的來源。 也因著長餘暉材料的顏色有限（比如沒有接近印鐵所常用 的CMYK四主色，甚至連純白色也還未開發出來），材料的粒徑 偏大（約5~200ym)難以直接用市面上現成的半色調網印設備 1373742 * _印製，所以無法適用於全彩的網點印刷，以致於難製作出精美 的全彩夜光圖。以熱為能源者更是未見有類似的產品。月、 目前可找到最接近的產品為門牌的印刷，其製作方式為在 PVC (或金屬品）上塗上一般的漆料後，於預留的地方再欲 顯示夜光的字（中國專利字號〇199104693 5)，因此所顯示出來 的子大都是單色。如附件一所示的三個成品。 本案因涉及要採用彩色半色調網點印刷的特殊須求，而目 前使用的夜光材料的特性與印鐵不相容（因厚度的關係）。現今 •夜光漆在市面上使用很興旺時，唯獨欠缺全彩網印（不僅限^ 金屬品）的應用。本發明人也是嘗試數年才突破相容性的問題。 目刖市面上的夜光產品所用的基材大都不同於本案，其製 程、漆料、製作方式、運用的機具都不同，如常用的陶究類、 玻璃、織物、塑膠等，其各自有特殊的優勢。至於現今市面上 既有的夜光平面印刷產品很容易被本發明所取代。因本發明的 技術可製作出精美的全彩夜光圖。本發明產品不但可承襲既有 _ fan的及取篡外線或可見光後產生長餘暉的夜光功能，也可因 著*、’、源（氣熱或水熱）同樣也可產生長餘暉的夜光功能。加上本 案是利用半色調的網點印刷，在色彩的艷麗與精緻上遠超過市 面上類似的平面產品。 現有市面上夜光產品只是利用夜光材料本身的餘輝與顏色 ，現在基材上的一部份區域，大都以實色印刷方式為主，也就 色的表現上較為單調。加上其夜光漆只是塗在整個面的 4伤而已，因此整體的發光亮度會因所佔面積多寡而打折扣。 本案的產印為利用微米材的長餘暉當成亮度的來源塗佈在 整片基材（或金屬），在其上加上彩色半色調網點圖以顯示出鮮 7 1373742Ll,: The raw materials of Yiguang products are the same. The difference is that the invention focuses on the research (4) in color printing, that is, not only requires good night light, = the graphic effect of the screen printing. At present, the development of luminous products is based on the United States - Japan and the big 13⁄4 is the world's major town. The products of the present invention have clear advantages over the existing luminous products currently available on the market, and will bring more extensive space for the application of luminous products. • The research on the development of Changyu Zen luminescent materials has made great progress. The brightness and quality of the materials developed have also made great progress. However, the long ember luminescent material cannot be used as the final product, and must be processed and remanufactured with other materials to be applied in daily life. Therefore, in recent years, many related application technologies have gradually developed. At present, in the field of luminous printing, the existing products seem to focus on the simple signboard. The β process is to print the pattern first, and then the long-lasting micro-particles are poured into the transparent paint t and printed on the light-colored part of the substrate. Think of it as a source of color and night light. Also because of the limited color of the long-lasting materials (such as the CMYK four main colors not commonly used in printing iron, even pure white has not been developed), the material particle size is too large (about 5~200ym) is difficult to use directly on the market. The ready-made halftone screen printing equipment 1373742 * _ printed, so it can not be applied to full-color dot printing, so that it is difficult to produce a beautiful full-color luminous map. Those who use heat as an energy source have not seen similar products. In the month, the closest product can be found for the printing of the house. It is made by applying the general paint on the PVC (or metal) and then displaying the word of the night light in the reserved place (Chinese Patent No. 〇199104693) 5), so the sub-displays are mostly monochrome. Three finished products as shown in Annex 1. This case involves special requirements for color halftone dot printing, and the properties of the currently used luminescent materials are incompatible with the printed iron (due to thickness). Nowadays, when the luminous paint is very prosperous in the market, it is lacking in the application of full-color screen printing (not only metal products). The inventors have also tried to break through the compatibility problem for several years. Most of the substrates used in the luminous products on the market are different from the case. The processes, paints, production methods and tools used are different, such as commonly used ceramics, glass, fabrics, plastics, etc., each with special Advantage. As for the existing luminous flat printing products available on the market today, it is easily replaced by the present invention. The fine full-color night light map can be produced by the technique of the present invention. The product of the invention can not only inherit the luminous function of the _ fan and the long afterglow after taking the outer line or the visible light, but also can generate the long-lasting luminous function due to the *, ', source (gas heat or water heat). . In addition, the case is printed by halftone dot printing, which is far superior to similar flat products on the market in terms of color beauty and exquisiteness. The existing luminous products on the market only use the afterglow and color of the luminous materials themselves. Now, most of the areas on the substrate are mainly printed in solid color, and the color is more monotonous. In addition, its luminous paint is only applied to the entire surface of the 4 injuries, so the overall brightness of the light will be compromised due to the amount of area. The production of this case is to use the long afterglow of the micron material as a source of brightness to coat the entire substrate (or metal), and add a color halftone dot pattern to show the fresh 7 1373742

[Description of the Invention] 8 The purpose of the present invention is to see that the color halftone has a clear_light_, which will make people, after the slave, when the time is in the dark, the luminous material is oblique ^ Yang Wei half color reward ^ 卩Qing·color luminous pattern. The technical means adopted by Mingli invention include: the source of the material used for reading (_color), the luminous material = luminescent ink and the lithographic ink is coated on the substrate by screen printing technology ( Or a metal piece), and then a (four) color halftone mesh 2 pattern is printed on the luminescent ink, and the color of the succinct color is pure. [Embodiment] I. Basic features and characteristics of the present invention The present invention will have long afterglow characteristics. Shi Xi Shao acid salt (Qing 4 must do 3 meters of material to add color halftone dot printing. In addition to maintaining the bright, delicate and delicate halftone dot pattern of the original iron, the night light is also full The pattern effect I can generate long-lasting luminous light after the stimulation of the heat source, in addition to the warp or visible light, and the appearance of the product can be easily processed into various kinds. The invention places a luminous material on a substrate (such as a metal or other planar material) and then prints a color halftone dot. When there is a clear light source, such as during the day, it will be seen to be printed by colored halftone dots. The color pattern. However, after a period of stimulation by a general light source (preferably ultraviolet light) or a heat source, the night light material acts when the P is produced. The source of the night light micron particles on the primer passes through the halftone. After the transparent color pattern printed on the dot, the pattern or text of the '" will be made. To the full color 1373742 The invention is made of metal (other substrates can also be used), so that the product will emit halftone color night light to increase The application and function of the product. The light-emitting material in the luminescent ink is used as the light source, and the color pattern printed by the halftone dot is used as the color source. This results in a delicate and exquisite full-color graphic in the night light. The luminous material needs to be first After the light is stored, the effect of the long afterglow can be obtained. However, since the substrate of the present invention is a metal, the inventors have found that the heat source can also make the luminous material light (the opposite effect of the cold source), thereby further expanding the application range of the present invention. The above concept was reached. After several years of research, the inventors finally made a finished product into 7. The long-lasting luminescent material currently used is yttrium aluminate. Micron material (& Sapporo 4: The office is most optimistic, the invention uses this material. = The particle size of this material is too large (60~150μπι), it must be gathered to emit brighter light and maintain The invention thus separates the printing of the luminescent material from the halftone color printing; that is, when displaying luminous light, the former is responsible for illuminating, and the latter is responsible for color. It does not affect the environment of general brightness (such as daytime). The printing process of the invention shows that the substrate of the invention (such as metal sheet, pvc, wood f or glass sheet is first coated with a paint layer (-usually white) or printed with a layer of fluorescent paint, Above; coated with a transparent ink filled with a micro-material of dream (four) salt 'this layer must pay special attention to the problem of the concentration of micro-materials, the general application hopes to turn to the lion: the two questions asked:) 'The brush will also face The printing ink used in the bubble is bis- 11 · The principle of the invention i · The principle of luminescence The luminescent material is mainly composed of a compound (matrix) as a host and a specific small amount of impurity ions (10 1373742 f - Activator) to improve the light of the luminescent material Performance, again adding another impurity ions as a sensitizer. These impurity ions will replace the ions in the original lattice of some of the matrix crystals, causing the lattice of the matrix to be trapped, resulting in traps that can capture the excited electrons. The deeper the trap, the longer the afterglow. The activator is a luminescent center that is excited by external energy to produce a luminescent phenomenon. The sensitizer is added to effectively absorb the excitation energy, and the sensitizer transfers energy to the activator to achieve energy efficiency. Taking the SrAl2〇4:Eu2+,I)y3+ luminescent material as an example, Eu2+ is the luminescence center in the material, while the Thai Dy3+ ion is the trap center' can effectively capture and store the excited electrons, which produces time. Up to 2000 minutes of afterglow. When the luminescent material is excited by energy, an electron-hole pair is generated, in which most of the electrons and holes are quickly combined, and the characteristic spectrum of the material is released, and a small part of electrons and electricity are generated. The holes are trapped in the defects or trapping centers of the material itself. 'Because these traps have low energy at the center of the trap, the excitation energy stops irradiating, and after the heat activation at room temperature, it is enough to slowly get out of the trap. The electrons and holes again recombine and release energy in the form of light, which is the afterglow phenomenon. Figure 1 shows the electron, hole trap and electronic transitions of the luminescent material after excitation. The order is: (a) excitation, (b) electron trap, (c) electron depletion, (d) and (g). ) Electron and hole recombination, (e) hole trap, (f) hole removal, (h) direct recombination and other processes. In terms of energy, the electrons in the material absorb the excitation energy and convert the energy into a form of potential energy storage. In the case of no vibration, the radiation is released when the bonding process returns to the ground state. The change in potential energy is shown in Figure 2 as a plot of the positional energy and coordination coordinates. The position of point A is the ground state.

Nanotechnology actually has no definition of the system. The general term means that the material exhibits physical, chemical or biological properties and phenomena at the nanometer scale that are different from the giant scale. Mitech uses this knowledge to operate and control atoms or molecules in a tiny world of nanometer-scale to form new nanoscale structures (nanomaterials) to reveal new functions and characteristics. , the general term for designing, manufacturing, or assembling a new material device or system to produce new functions and to utilize it. The luminescence phenomenon of Changyu Zen luminescent material comes from the replacement of ions on the crystal lattice, and the beginning of the long afterglow of The method of making nano-materials is also commonly used. Therefore, the long-lasting luminescent material is also made by controlling the molecular composition, and can also be called a nano material. φ 诅· The manufacturing method of the present invention, the printing part of the luminescent ink of the present invention, It is divided into two steps. The following is a basic description of the two printing methods. i. Screen printing screen printing, also known as through hole method (p〇r〇uS) or mime printing method (stenc i 1), the ink Add to a screen with a fine mesh screen, use the scraping action of the scraper to let the ink pass through the fine holes to the paper or articles placed under the net. The parts that do not need to be printed are manually or outside the screen. The machine is made of a negative wax plate for protection. Screen printing is a versatile printing 'materials other than paper, such as clothes, ceramic tiles, tea sets, electrical appliances, large billboards, circuit boards, computers, computers and high-tech related products. Can be engaged in less s, a variety of printing, has become a technology in the high-tech electronics industry is not a. The second picture above is the Sichuan Mesh screen and scraper used in the screen printing of the invention. ii. The entire surface of the table is printed in the printing process, and the images are all adjusted by the density of the dots. The color and color are displayed through the mixing and overlapping of the basic color dots. There are two different types of outlets used in technology: amplitude modulation network points and FM network points. Solid-kapped 1^ network points are currently the most widely used network points. Their dot density is in ^, by adjusting the size of the network dots to express The color depth and different color tones. Fine; I, medium, mainly consider the size of the dot, the shape of the dot, the angle of the dot and the thickness of the wire. The figure below shows the effect of different dot sizes. The part represents the coverage of the ink. The color graphic f-knife of the present invention adopts this method. The FM network dot is a newly developed screen printing method after the 1990s, and the difference between the fish tuning and the Liuxing control point is that the frequency modulation is frequency modulation. The dot size of the dot is fixed, and the color and tone are presented by the density of the dot. Some of the highlights are denser than the " darker part. The primer portion of the present invention is in this manner. IV. Experimental Example of the Invention In order to enhance the brightness of the luminescent ink after printing, and to achieve the effect of color luminous light, the present invention applies a white opaque lacquer to the substrate in the printing method of the experimental example, and then transparent. The luminescent ink is screen-printed as a substrate, and the two-step composite printing of the color ink is covered by dot printing, and the detailed experimental procedure is as follows. 1373742 'The experimental example of the invention uses the two-step printing method of screen printing and dot printing' to combine the transparent luminescent ink and the color ink on the iron sheet, in order to achieve the effect of luminous enhancement and full-color luminous light ^ by illuminance measurement Determine the influence of time on the brightness of the luminescent ink, and explore the influence of the water resistance and temperature of the luminescent ink on it. To this end, the present invention conducted the following experiment on a luminescent ink. i. Experimental example of composite printing of luminescent ink of the present invention This experimental example does not consider the thickness problem, and is based on the premise of greatly improving the illuminating brightness. Lu uses a two-stage composite printing technique in which screen printing and dot printing are combined. In the case of considering the illuminating effect, this experiment uses the iron sheet printed with white ink as the bottom, first printing a layer of luminescent ink on the iron sheet by screen printing, and then printing the color ink on the luminescent ink layer by dot printing. High-intensity illumination and color luminous effects are achieved by the high density of screen printing and the translucency of dot-printed color inks. The equipment of this experimental material is shown in Table 1. Table 1 List of light-emitting ink composite printing experimental materials and equipment.

The left and lower left images in Annex 3 show the screen printing results of 20% and 50% luminescent inks in bright places respectively. The attachments = upper right and lower right respectively show their illuminating effects in the dark. (4) The iron sheet printed with a layer of luminescent ink is printed on the color ink layer. The upper part of the attached figure and the figure below show the color pattern printing of 20% and 50% of the luminescent ink in the bright place respectively. The upper picture and the lower picture of the annex 5 respectively show the illuminating effect in the dark place. (5) Observe the illuminating effect of the printed iron piece and observe the distribution of the luminescent material particles and measure the thickness of the finished product with the ultra-close-range photographic system and the thickness gauge. The result of the Manchester A ink composite printing experiment is as follows: It can be seen from the luminescence phenomenon of the finished product printed in the attached figure below. The composite printing method used in this experimental example is better than the dot printing method alone. It can be said that it exhibits different effects, not only the brightness of the light is greatly improved, but also the effect of colored luminous. The following is a discussion of the appearance, luminescence efficacy and luminescent particle distribution of the finished product. # Firstly, in the luminous performance part, it can be seen from the comparison of the above figure and the following figure. As the concentration of the luminescent ink increases, not only the illuminance is increased, but also the color effect and level are more obvious. It can be seen from the comparison of the illuminating material of the illuminating material in the upper part of the sixth and the 60% printed product below, 6 〇% of the printed product has a very good effect on the brightness performance. In the appearance part, it can be seen from the left and lower left figures in Annex III that as the concentration of the luminescent ink increases, the color of the screen printing layer also becomes darker, and the luminescent material of the over-ice is yellow-green. It affects the primary color to be presented in color graphics as shown in the figure below in Annex 4. Although the high-concentration luminescent ink can give a better illuminating effect in the dark, it will also make the original design of the white-based color pattern have a bias effect on the color performance in the bright place. In addition, the concentration determines the cost of the luminescent ink. Therefore, how to find the best concentration ratio from the illuminating effect and the appearance color is the future application. In the following experimental examples, the measurement of illuminance will be used to find out the luminescence of each concentration ratio. The efficiency can be used as a reference for post-mortem applications. In the luminescent particle distribution part, the luminescence phenomenon of the right and left right images of Annex III can be compared. The luminescent particle distribution of 20% of the printed samples is obviously sparse, and as the concentration increases, the particle distribution tends to be dense. The illuminating effect is also more saturated. With the super close-range photography system, the difference in the distribution of luminescent particles at different concentrations can be seen. The upper and middle images of Annex VII are close-up images of the white parts of the finished prints at concentrations of 1〇% and 〇%, respectively. It can be seen from the comparison of these two figures that the distribution of luminescent particles of 6〇% finished products is obviously much denser than that of 10% finished products, and there is even a phenomenon of particle stacking. @@也也也是高浓度印刷 "Products with higher brightness main reason. The high density of the luminescent particles is not only high in luminance, but also the mutual excitation of the particles illuminates each other to extend the phase of the illuminating afterglow. If we compare the close-up image of the 10% finished product of this experimental example (as shown in the attached figure above), the attached figure of the screen is only 70% of the close-up image. It can be clearly seen that at the same magnification, The number of luminescent particles distributed on a unit surface area varies greatly, and this is why the composite printing method can be greatly improved in brightness. In addition, the thickness of each printed layer and different density printing can be obtained by the measurement of the digital thickness meter. The measuring instrument is shown in the figure above in the attached figure, and the thickness measurement results of each layer are compiled into Table 2. It can be seen from Table 2 that as the concentration of the luminescent ink increases, the thickness of the screen printing layer also increases, which also shows that the high concentration of 1373742 luminescent ink has a higher stacking phenomenon of luminescent particles and higher brightness. the reason. 3(a) and 3(b) are schematic longitudinal cross-sectional views of the composite printed product and the general dot printed product of the present invention, respectively, and the difference in the distribution thickness of the luminescent particles of the two different printing methods can be seen. The finished product comprises a metal sheet (10) as a substrate, and at least one layer is mixed with a luminescent ink (20) comprising a luminescent material and a transparent ink, which is printed on the metal sheet (10) by screen printing technology; A color ink layer (3 inch) printed on the luminescent ink layer (20) by a color halftone dot printing technique.

Therefore, the experiment will measure the illuminance of the luminescent ink with time by the measurement of the illuminometer. The decreasing trend, and through the comparison with the brightness of the luminescent materials, to explore the luminous efficacy and characteristics of each concentration, as a reference for the application of the future luminescent ink. The experimental materials are shown in Table 3.

(2) Repeat steps (1) for 5 minutes, 1 minute, 15 minutes, minutes, 90 minutes, and 120 minutes of excitation time, respectively.

The brightness measurement position of this step is as in the range of the red circle in Annex IX. The experimental results and discussion of the influence of time on the brightness of the luminescent ink are as follows: The illuminance meter used in this experiment, as shown in the figure below in Annex 8, the minimum scale is O.Ollux, lux (lux) is the unit of illumination, which is defined as the incident luminous flux. (lumen) The ratio of the surface to the illuminated surface (m2), where the luminous flux is all the light-emitting energy emitted by the light source and perceived by the human eye. Even if the brightness is 0.01 lux, it can be seen in the dark. The luminescence phenomenon. Due to the limitation of the instrument scale, the measurement data of this experiment is only 0.011 ux. Generally, the definition of luminous is 0.000321 ux as the lower limit of visible light. The research results of this experiment can mainly be from luminescent materials and luminescence. Ink screen printing The brightness measurement results of the product and the color printing finished product of the luminescent ink are discussed, and the luminous efficiency of each printing layer is discussed by comparing with the brightness of the luminescent material. First, in the luminescent material part, Figure 4 The time decay curve of the afterglow brightness can be seen that the attenuation of the brightness at different time excitations can be said to be quite 1373742.
，* I -近似的，這可說明本實驗所使用之發光材料有一定的性質穩定 性。此外，由衰減曲線可以看出，發光材料亮度的衰減在餘輝 時間前5分鐘較為急遽，5分鐘之後則漸趨平緩，而不同激發 時間所造成的亮度差距也是在前5分鐘較為明顯。由圖中亦可 發現’激發時間的增長對發光亮度的提升也有很明顯的影響， •而激發時間超過30分鐘後，其亮度的衰減曲線則相當接近，故 可推測本實驗所使用之發光材料’在1601ux光源的激發下，其 亮度飽和所需的激發時間為30分鐘。這也與參考文獻【6】中 •提到的，在2001UX光源的激發下，亮度飽和所需的激發時間為 30分鐘相當接近。此現象亦可由圖5不同量測時間下，激發時 間與餘輝亮度的關係圖可以看出，激發時間在30分鐘以上，各 量測時間所得到之餘輝亮度趨於穩定，相對地，在激發時間小 於30分鐘的情況下，由於發光材料能量的吸收未達飽和，故所 測知·的餘輝亮度則變化較大。此外’由圖6本實驗發光材料與 參考文獻【5】中相同發光材料之相對照度趨勢圖可以看出，兩 鲁種材料在亮度遞減的趨勢上是非常接近的，這也顯示本實驗使 用之照度計有一定的準確度。 在發光油墨網版印刷樣品部分，濃度配比！〇%之初始激發 亮度小於O.Ollux，故無法量測。圖7〜11所示為60%〜20%五種 配比濃度，分別在30分鐘、60分鐘、90分鐘與120分鐘激發 時間下’其餘輝亮度對量測時間的衰減趨勢圖。由圖7與圖8 可以看出’ 60%與50%發光油墨樣品在四種激發時間下，其衰 減曲線是相當接近的，故可知在“⑴狀的光源下，其達飽和亮 度所需的激發時間為30分鐘。相對地，20%〜40%由於亮度較 小’加上照度計的精度有限，故會有較大的誤差，看仍可看出 19 1373742 -其達飽和亮度所需的激發時間转為3G分鐘。 >圖^所示為6G%〜2G%五種濃度配比與發紐料對照的相 對党度衰減趨勢圊’激發時間為3〇分鐘，由圖中可以看出，知 %和60%的衰賴勢與發储料十分接近，這說明此兩種濃度 配比的發光油墨，仍保有相當不錯的發光材料特性。而4〇%以 下的二種配比發光油墨，則有量測上的誤差存在。 本實驗將不同濃度配比於各時間點所測得之亮度與發光材 料測得之亮度的比值作為發光效能。圖13所示為6〇%〜2〇%五 擊種濃度配比與發光材料對照的發光效能曲線圖，由圖中曲線可 以看出，發光效能有隨著時間而遞減的現象，不同濃度配比的 效能差異在餘輝時間前5分鐘較為明顯。而由準確度較高的濃 度50%與60%之效能曲線可以看出，量測時間前兩分鐘的亮度 效能起伏變化較為平穩，且濃度20%僅能測得前兩分鐘之亮 度’故本實驗各濃度配比的發光效能即以量測時間2分鐘以 前’四個時間測點的發光效能平均值來做為依據，整理成表5。 表5光源I601ux激發時間30分鐘各濃度前兩分鐘之發光效能表 灑度配比 平均發光效能 20% 4.2¾ 30% 7.2% ' 40% 14.7% 50% 35.2¾ 60% 46.1¾ 發光油墨彩色印刷成品部分，在量測位置的選擇上，主要 是想觀察彩色油墨對發光效能的影響，而彩色油墨處的發光亮 度除了受其底下發光油墨層的影響之外，亦與周遭不同顏色的 亮度有關，故選取此處既有彩色油墨覆蓋，周圍又有較高發光 亮度的色系來做模擬。而經由量測其餘輝亮度發現，僅有濃度 配比40%、50%與60%之初始激發亮度大於O.Ollux，其中40 %之初始亮度僅為〇.〇61ux，其餘濃度配比則無法量測。圖14 20 1373742 · * « -所示分別為5G%和60%其網版印刷鄉色印刷之亮度衰減趨 勢圖’由®中可以看出，經過彩色印刷其亮度明顯降低很多， 但其衰減趨勢仍是相當接近的。此外，也可看出不同濃度配比 與印刷步驟對餘輝亮度的影響，在餘輝時間前5分鐘較為明 顯。若同樣地取餘輝時間前兩分鐘的平均發光效能，可得到彩 色印刷50%與60%其發光效能分別為4 5%與8 4%，相較於網 版印刷的發光效能可發現，再經過彩色網點印刷的步驟，會使 發光效能再降低80%以上，不過這會因彩色印刷圖案的不同而 攀有所改變。 本發明之發光油墨耐水性測試 根據參考文獻【6】，發光材料的耐水性較差，在水中會慢 慢地分解，使發光性能下降。因此本實驗將透過發光油墨網版 印刷樣品浸水後亮度的量測，探討發光油墨之耐水性，來了解 油墨對發光材料的包覆情形。另外也對本實驗所用之發光材料 遇水後的變化作觀察。 φ 本發明發光油墨耐水性測試步驟如下： (1) 將長餘陣發光材料加入裝有水的透明容器中，均勻混 .合後，靜置兩天觀察其現象。 (2) 分別將20%、30%、40%、5〇%與60%之發光油墨網 版印刷樣品浸置於水中兩天後取出，以1601ux光源激發30分 鐘後再以照度計量測其亮度變化，並與未浸泡水之樣品亮度作 比較。 本發明路油羃耐水性實驗結果輿討論： 長餘暉發光材料經過兩天的浸泡之後，發現在沉澱的發光 材料上方與水面接觸的地方，出現一層白色物質，如附件十上 21 1373742 1所示。初步推測可能為發紐料製造過程中摻人的雜質，或 者是發光材料與水作用分解出的物f ^於是湘白色物質密度 較低的特性，將其與發光材料分離出來，並再次加水於發光材 料中’重複這兩個步驟，附件十下0所示為分離出之白色物質。 結果發現，多次與白色物質分離後之發光材料，再經過水的浸 泡後，仍會產生新的一層白色物質，故可進一步確定此白色物 質為發光材料水解的產物，而這也就是發光材料效能會降低的 原因。 丨發光油墨方面，在經過兩天的浸泡之後發現，其亮度並沒 有出現明顯的改變’如圖15所示，可以看出發光材料含量較高 的50%與60%樣品’其亮度衰減曲線與未浸水之樣品相近，這 也顯示油墨對發光材料有著良好的包覆性，使發光油墨有著良 好的对水性。 主發明溫膚對發光油墨亮度之影響枓測封 根據觀察，發光油墨對突然增高的溫度會有亮度提升的現 象，而急遽的降溫則會使亮度驟減，故可知溫度對發光油墨有 一定的影響性^本實驗將藉由長時間的高溫，來探討發光油墨 的财熱性。 本發明溫度對發光油墨亮度之影響性測試步驟如下： (1) 將濃度配比50%與60%之網版印刷樣品置入溫度保持 為85 C的熱水中，靜置60分鐘，取出後擦乾，以16〇hjx光源 激發30分鐘，量測其亮度。 (2) 將測得的亮度資料與未加熱之樣品資料做比較，並繪 圖討論。 22 1373742 ’ 遇度對發光1 墨亮度^影響基與討論： 發光油墨樣品在經過60分鐘的加熱後，其外觀顏色上有變 暗的現象’附件十-上圖與下圖所示分別為5〇%樣品加熱前後 的顏色。而在亮度量測結果的比較上發現，經過加熱之樣品， 其發光效能有變低的現象，圖16所示為濃度5〇%與6〇%樣品 加熱前後亮度衰減曲線的對照圖，可以看出經過實驗加熱後， 各量測時間的餘輝亮度皆有降低的現象。而在彩色網點印刷的 步驟巾，會經過16(Tt供烤數分鐘的手續，這也是降低彩色印 刷發光效能的影響因素之一。經由本實驗可知，長 狀態將會降低發光油墨的發光效能。 、 。服 柩據實驗結果太發明路現下列四點： ⑴在不添加雜咖情況下，㈣水加熱法，發捕料與 透明油墨的濃度配比上限約為7〇%。 (2)透明發光油墨採用網版與網點兩步驟複合式印刷法，可 在鐵片上呈現出明顯的彩色夜光效果。 籲 （3)透明發絲墨仍保有相當不錯的發紐料特性，其亮度 的衰減趨勢在餘輝時間前5分鐘最為急遽，之後則漸料緩。 •而不同激發時間西己比濃度與印刷步驟對亮度的 •輝時間前5分鐘较為明顯。 警 (4)透明發光油墨在咖性方面，雖然有良好的耐水性，但 在長時間高溫的條件下，會有發光效能降低的現象。 本發明採用的複合式印刷方法已得到了不錯的成效。但在 發光亮度與效能方面，一種可行的實施方式係添加稀釋劑（或 軟化劑），藉由蒸發性稀釋劑對拌合1作_作用，來增加發光 23 . 1373742 .* * 墨^翻免度提升的效果。其次，若採用混凝土 硯必目刖在發光油墨中’加入粒徑較小的發光粉末，也 可用來填補大粒徑發光粒子間的空隙，達到亮度的提升，作須 注意的是，過小粒經的發光材料，其亮度也會相對降低。而大 小粒徑發光材料的不同排列搭配印刷，也可藉由其發光亮度的 •差異，來達到發光_特殊效果。此外，也可藉由搭配不同色 系的發光材料，利用其發出的各種色光，來增加彩色夜光的效 果，其中，硫化物體系發光材料的顏色豐富，便是可以使用的 •一種材料。 本發明透過實驗發現溫度對發光油墨的亮度效能有很大的 影響性，這方面可藉由定溫系統，如供箱，來更加了解發光油 墨在溫度方面的影響機制，增加發光油墨應用上的參考依據。 VI.結論 由上述之說明可歸納本發明具有下列之優點： 1本發明成除了具無毒、環保、節能等特性外；它具 _有很多的獨特性，因此可應用的產品範圍應可持續的闊大，如 熱的應用、以及精美彩色半色調網點印刷等就有很大的空間。 2 .消防安全：可提供當有災害發生而人工光源失效時，本 產品可以提供逃生所需微光供指示標誌、逃生路線、或消防設 備等標示。 3·本發明成品不但可提供較一般市面上微光產品有更良 好的被光效果’而且可用金屬品上全彩的顏色特性發揮出更好 的特效。 4 ·防偽機制.由於目前具夜光全彩（半色調網點印刷）印 24 1373742 •鐵的產品尚未出現。縱使有人可以製造出來，其半色調網點印 刷、製程、以及漆料的調配等都會造成不同的效果，因此容易 辨識出產品的差異。 5 ·夜光產品：如禮品，現代藝術晝及照片（附件十二） 等。因著全彩（半色調網點印刷）夜光效果可創造出細膩的夜光 圖形與顏色。另在標示牌（如路標、門牌、道路攔竿標線、汽機 車車牌等）的使用上在很多國家已用法規規定必須具備。本發明 使這些產品的圖文變得更精緻。, * I - Approximate, which indicates that the luminescent materials used in this experiment have certain property stability. In addition, it can be seen from the attenuation curve that the attenuation of the brightness of the luminescent material is more rapid 5 minutes before the afterglow time, and gradually becomes smoother after 5 minutes, and the brightness difference caused by different excitation times is also obvious in the first 5 minutes. It can also be seen from the figure that the increase of the excitation time also has a significant effect on the improvement of the luminescence brightness. • After the excitation time exceeds 30 minutes, the attenuation curve of the brightness is quite close, so the luminescent material used in this experiment can be inferred. 'The excitation time required for saturation of the brightness of the 1601ux source is 30 minutes. This is also mentioned in reference [6]. Under the excitation of the 2001 UX source, the excitation time required for brightness saturation is quite close to 30 minutes. This phenomenon can also be seen from the relationship between excitation time and afterglow brightness under different measurement time in Fig. 5. It can be seen that the excitation time is more than 30 minutes, and the afterglow brightness obtained by each measurement time tends to be stable. When the excitation time is less than 30 minutes, since the absorption of the energy of the luminescent material is not saturated, the detected afterglow brightness changes greatly. In addition, from the trend graph of the same luminescent material in the experimental luminescent material of Fig. 6 and the reference [5], it can be seen that the two ruthenium materials are very close in the trend of decreasing brightness, which also shows that the experiment uses The illuminometer has a certain degree of accuracy. In the luminescent ink screen printing sample part, the concentration ratio!初始% of the initial excitation brightness is less than O.Ollux, so it can not be measured. Figures 7 to 11 show the attenuation trend plots of the remaining luminance versus the measurement time for the five concentration ratios of 60% to 20%, respectively, at 30 minutes, 60 minutes, 90 minutes, and 120 minutes of excitation time. It can be seen from Fig. 7 and Fig. 8 that the attenuation curves of '60% and 50% luminescent ink samples at four excitation times are quite close, so it is known that under the "(1)-like light source, it is required for saturation brightness. The excitation time is 30 minutes. Relatively, 20% ~ 40% due to the small brightness 'plus the accuracy of the illuminometer is limited, so there will be a large error, you can still see 19 1373742 - it needs to reach saturation brightness The excitation time is changed to 3G minutes. > Figure 2 shows the relative concentration attenuation trend of the five concentration ratios of the 6G%~2G% and the sputum control. The excitation time is 3〇 minutes, as can be seen from the figure. Knowing that % and 60% of the fading potential are very close to the hair storage material, which indicates that the two kinds of luminescent inks of the same concentration still retain quite good luminescent material characteristics, and the two kinds of luminescent inks below 4% by weight. There is an error in the measurement. In this experiment, the ratio of the brightness measured at different time points to the brightness measured by the luminescent material is used as the luminous efficiency. Figure 13 shows 6〇%~2〇 The luminous efficacy curve of the concentration ratio of the five-stroke species and the luminescent material, It can be seen from the curve that the luminous efficacy decreases with time, and the difference in potency of different concentration ratios is more obvious 5 minutes before the afterglow time, while the performance curves of 50% and 60% with higher accuracy can be It can be seen that the brightness fluctuations of the first two minutes before the measurement time are relatively stable, and the concentration of 20% can only measure the brightness of the first two minutes. Therefore, the luminous efficiency of each concentration ratio in this experiment is measured 2 minutes ago. The average of the luminous efficacy of the four time points is used as the basis, and is compiled into Table 5. Table 5 Light source I601ux excitation time 30 minutes The first two minutes of each concentration of the luminous performance table sprinkle ratio average luminous efficiency 20% 4.23⁄4 30% 7.2% ' 40% 14.7% 50% 35.23⁄4 60% 46.13⁄4 The color printing finished part of the luminescent ink. In the selection of the measuring position, it is mainly to observe the influence of the color ink on the luminous efficiency, and the brightness of the color ink is except In addition to the influence of the underlying luminescent ink layer, it is also related to the brightness of different colors around it. Therefore, it is selected to have both color ink coverage and a color with high illuminance around it for simulation. By measuring the remaining brightness, it is found that only 40%, 50% and 60% of the initial excitation brightness is greater than O.Ollux, and 40% of the initial brightness is only 〇.〇61ux, and the remaining concentration ratio is Unable to measure. Figure 14 20 1373742 · * « - 5G% and 60% respectively show the brightness decay trend of screen printing in the screen printing'. It can be seen from the ® that the brightness is significantly reduced after color printing. However, the attenuation trend is still quite close. In addition, it can be seen that the effect of different concentration ratios and printing steps on the afterglow brightness is more obvious 5 minutes before the afterglow time. If the same afterglow time is taken two minutes The average luminous efficiency can be 50% and 60% of color printing, and the luminous efficacy is 45% and 8 4%, respectively. Compared with the luminous efficacy of screen printing, the color printing process can be used to make the light. The performance is reduced by more than 80%, but this will change due to the difference in color printing patterns. The water resistance test of the luminescent ink of the present invention According to the reference [6], the luminescent material has poor water resistance and is slowly decomposed in water to lower the luminescent property. Therefore, this experiment will measure the brightness of the luminescent ink after immersing the water through the luminescent ink screen to understand the coating of the luminescent material. In addition, the changes in the luminescent materials used in this experiment after water contact were observed. φ The water resistance test procedure of the luminescent ink of the invention is as follows: (1) The long residual luminescent material is added into a transparent container filled with water, uniformly mixed, and then allowed to stand for two days to observe the phenomenon. (2) 20%, 30%, 40%, 5%, and 60% of the luminescent ink screen printing samples were respectively immersed in water for two days, and then taken out, excited by a 1601 ux light source for 30 minutes, and then measured by illuminance. The brightness changes and is compared to the brightness of the sample that is not soaked in water. The experimental results of the water resistance test of the road oil sputum of the present invention are discussed. After the immersion of the long-lasting luminescent material for two days, it is found that a layer of white matter appears in the place where the precipitated luminescent material is in contact with the water surface, as shown in Attachment No. 21 1373742 1 . Preliminary speculation may be the inclusion of impurities in the manufacturing process of the enamel, or the decomposition of the luminescent material and water f ^ then the density of the white matter is lower, separate it from the luminescent material, and add water again In the luminescent material, the two steps are repeated, and the white matter separated is shown in the following 0. It was found that the luminescent material separated from the white matter after many times, after immersion in water, still produced a new layer of white matter, so it can be further confirmed that the white substance is a product of hydrolysis of the luminescent material, and this is also a luminescent material. The reason why performance will decrease. In terms of luminescent inks, after two days of immersion, the brightness did not change significantly. As shown in Fig. 15, it can be seen that the 50% and 60% samples with higher luminescent materials have a brightness decay curve. The samples that are not immersed in water are similar, which also shows that the ink has good coating property to the luminescent material, so that the luminescent ink has good water repellency. The effect of the main invention of warm skin on the brightness of the luminescent ink 枓 封 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据 根据Influential ^ This experiment will explore the finernity of luminescent inks by long-term high temperature. The test procedure for the influence of the temperature of the invention on the brightness of the luminescent ink is as follows: (1) The screen printing sample having a concentration ratio of 50% and 60% is placed in hot water maintained at a temperature of 85 C, allowed to stand for 60 minutes, and taken out. Dry it and excite it with a 16 〇hjx light source for 30 minutes and measure its brightness. (2) Compare the measured brightness data with the unheated sample data and discuss it. 22 1373742 ' The degree of light on the light 1 Ink brightness ^ Influence base and discussion: After the 60-minute heating of the luminescent ink sample, the appearance of the color is darkened. Annex 10 - The above figure and the following figure are respectively 5 〇% of the sample before and after heating. On the comparison of the brightness measurement results, it is found that the luminescence efficiency of the sample after heating is low. Figure 16 shows the comparison of the brightness decay curves before and after heating of the samples at concentrations of 5〇% and 〇%. After the experimental heating, the afterglow brightness of each measurement time is reduced. In the step of printing on the color dot, it will pass 16 (Tt is used for baking for several minutes, which is also one of the factors that reduce the luminous efficacy of color printing. It can be seen from this experiment that the long state will reduce the luminous efficacy of the luminescent ink. According to the experimental results, the following four points are invented: (1) In the case of no adding coffee, (4) water heating method, the upper limit of the concentration ratio of the hair-catching material and the transparent ink is about 7〇%. (2) Transparent The luminescent ink adopts the two-step composite printing method of screen and dot, which can display obvious color luminous effect on the iron sheet. The (3) transparent hairline ink still retains quite good hair styling characteristics, and the brightness decaying trend is 5 minutes before the afterglow time, the most urgent, and then gradually slow down. • The different excitation time is more obvious than the concentration and the printing step on the brightness of the 5 minutes before the bright time. Police (4) transparent luminous ink in the coffee On the other hand, although there is good water resistance, there is a phenomenon that the luminous efficiency is lowered under conditions of high temperature for a long period of time. The composite printing method adopted by the present invention has achieved good results. In terms of illuminance and efficacy, a feasible embodiment is to add a diluent (or softener) to increase the luminescence by the action of the evaporating diluent on the mixture 1. 23373742 .* * Secondly, if concrete is used, it is necessary to see the addition of a small-sized luminescent powder in the luminescent ink, which can also be used to fill the gap between the large-sized luminescent particles to achieve an increase in brightness. The illuminating material passing through the small granules will also have a relatively low brightness, and the different arranging and illuminating materials of the size and size illuminating materials can also achieve the illuminating _ special effect by the difference of the illuminating brightness. It is used with different color luminescent materials to increase the effect of color luminous light. Among them, the luminescent material of sulphide system is rich in color, which is a material that can be used. The brightness performance of the ink has a great influence. In this respect, the temperature can be better understood by a fixed temperature system, such as a box. The influence mechanism increases the reference basis for the application of the luminescent ink. VI. Conclusion The above description can be summarized as follows: 1.
