Description

광변색 광고판{Photochromic Sheet}Photochromic Billboards {Photochromic Sheet}

본 발명은 조명의 투과에 의해 변색되는 광고판에 관한 것으로, 간판 등에 본 발명의 광고판를 설치하여 주간에 햇빛이 있는 상태에서는 광고판에 적용된 색이 보이고, 야간에 형광등 등의 조명을 통과시키는 경우 빛이 굴절되어 주간에 나타나는 염료에 따른 색상과 상이한 색으로 보이는 광변색 광고판에 관한 것이다.The present invention relates to a billboard that is discolored by the transmission of light, installed in the signboard, the billboard of the present invention to see the color applied to the billboard in the state of sunlight in the day, the light is refracted when passing the lights such as fluorescent lamps at night The present invention relates to a photochromic billboard that looks different from the color according to the dye appearing during the day.

일반적으로 아크릴은 메틸메타크릴레이트(methyl methacrylate)가 주 원료로써, 빛투과율이 92% 이상으로 투명도가 뛰어나고, 성형가공이 유리할 뿐만 아니라, 착색이 자유롭고, 표면 광택이 뛰어나므로 실내장식, 장신구, 간판, 조명기기, 디스플레이용 등으로 사용되고 있다. In general, acrylic is methyl methacrylate as the main raw material, which has a light transmittance of 92% or more, excellent transparency, favorable molding processing, free coloring, and excellent surface gloss. It is used for lighting, display, etc.

종래에는 디스플레이 하고자 하는 컬러를 발휘하기 위해서는 안료를 넣어 착색을 구현하거나, 칼라필름을 부착하여 원하는 색이 나타나도록 하고 있다. 그러나 상기의 두 방법은 모두 주간과 야간에 동일한 색상만을 제공하므로 광고 효과에서 식상해지는 단점이 있었다.Conventionally, in order to display a color to display, a pigment is put in to implement coloring, or a color film is attached to make a desired color appear. However, the above two methods provide the same color only during the day and at night, so there is a drawback in the advertising effect.

본 발명은 상기와 같이 단일 색상의 광고판을 주간에 햇빛에 의해 반사되어 나오는 컬러와 야간에 형광등과 같은 조명이 광고판을 투과하여 나오는 컬러와 다르게 함으로써 광고효과를 극대화 시킬 수 있는 새로운 방식의 가변 광고판을 제공하고자 한다.The present invention is a variable billboard of a new method that can maximize the advertising effect by different from the color of the single color billboard as reflected by the sunlight at daytime and the color such as fluorescent light at night passing through the billboard as described above. To provide.

상기를 위하여 본 발명자는 특정사이즈의 색처리가 된 가교고분자를 확산제로 사용하는 경우 광고판를 투과하는 빛이 굴절되어 주간에 염료에 따른 색상과 상이한 색으로 보이는 것을 발견하여 본 발명을 완성하였다.For this purpose, the present inventors have found that when the crosslinked polymer having a specific size of color treatment is used as a diffusing agent, the light transmitted through the billboard is refracted to look different from the color according to the dye during the day, thereby completing the present invention.

또한, 본 발명은 주간에 눈으로 보이는 색과 야간에 인공적인 조명을 통과시키는 경우 서로 상이한 색을 나타낼 수 있는 아크릴 조성물 및 성형체를 제공하고자 한다.In addition, the present invention is to provide an acrylic composition and a molded article that can exhibit different colors when the visible color at daytime and artificial lighting at night.

본 발명은 조명의 투과에 의해 변색하는 광고판에 관한 것으로, 간판 등에 본 발명의 광고판를 설치하여 주간에는 햇빛에 의하여 광고판에 적용된 염료의 색으로 보이고, 야간에 형광등과 같은 인공적인 조명을 광고판으로 통과시키는 경우 광고판에 적용된 색이 아닌 광산란에 의해 염료자체의 색과는 다르게 보이도록 하는 특수한 광고판에 관한 것이다.The present invention relates to a billboard that is discolored by the transmission of the illumination, the billboard of the present invention is installed in a signboard, etc. in the daytime to see the color of the dye applied to the billboard by sunlight, and to pass the artificial lighting such as fluorescent lamps at night through the billboard In this case, the present invention relates to a special billboard that makes it look different from the color of the dye itself by light scattering rather than the color applied to the billboard.

본 발명에 따르면, 투명고분자중합체 100중량부, 염료 0.01 ~ 0.5 중량부, 가교고분자에서 선택되는 평균입경이 0.1 ~ 0.5㎛인 색처리된 확산제 0.5 ~ 3 중량부로 구성된다.According to the present invention, 100 parts by weight of the transparent polymer, 0.01 to 0.5 parts by weight of dye, and 0.5 to 3 parts by weight of the color-treated diffusing agent having an average particle diameter of 0.1 to 0.5 µm.

본 발명에서 투명 고분자 중합체에 사용되는 수지는 광이 투과하는 투명한 수지라면 제한받지 않으며 예를 들면, 폴리메틸메타크릴레이트, 폴리스티렌, 폴리비닐클로라이드, 폴리아크릴로니트릴, 폴리카보네이트, 폴리설폰 및 그들의 공중합체에서 선택되는 어느 하나를 사용하는 것이 바람직하다.The resin used for the transparent polymer in the present invention is not limited as long as it is a transparent resin that transmits light, and examples thereof include polymethyl methacrylate, polystyrene, polyvinyl chloride, polyacrylonitrile, polycarbonate, polysulfone, and their air. Preference is given to using any one selected from coalescing.

중합체의 중합방법은 공지의 방법으로 제조 가능한 것으로서, 본 발명에서는 투명한 수지를 제조할 수 있다면, 제한되지 않으므로 더 이상 기재하지 않는다.Polymerization method of the polymer can be produced by a known method, and in the present invention, if a transparent resin can be produced, it is not limited and will not be described anymore.

본 발명의 염료는 통상적으로 고분자 수지에 사용되는 염료라면 사용가능하며, 사용되는 염료의 색에 따라 광고판의 색이 결정되는 것이므로 공지의 염료를 사용하는 것이면 제한되지 않는다. 염료의 사용량은 중합체의 함량을 기준으로 1 중량부 이하로 사용하며, 좋게는 0.01 ~ 0.5 중량부를 사용한다. 상기 범위를 벗어나는 경우 충분한 칼라효과가 없거나 투과 시 투과광에 의한 산란광의 색상이 선명하지 않은 단점이 있다.The dye of the present invention can be used as long as it is a dye usually used in a polymer resin, and the color of the billboard is determined according to the color of the dye used, so long as it is a known dye. The amount of dye used is 1 parts by weight or less based on the content of the polymer, preferably 0.01 to 0.5 parts by weight. If it is out of the above range there is a disadvantage that there is no sufficient color effect or the color of the scattered light by the transmitted light during transmission.

본 발명에서 사용하는 확산제는 비드상의 가교고분자인 것을 특징으로 하며, 폴리메틸메타크릴레이트(PMMA), 폴리스티렌(PS), 메틸메타크릴레이트-부타디엔-스티렌(MBS), 아크릴로니트릴-부타디엔-스티렌(ABS), 메틸메타크릴레이트-스티렌(MS) 수지 등에서 선택되는 어느 하나이상의 가교된 비드상의 고분자라면 가능하며, 본 발명의 상기의 비드상에만 한정되는 것이 아니며, 광을 산란할 수 있는 것이라면 어느 유기 고분자의 가교입자라도 가능하다.The diffusion agent used in the present invention is characterized in that the bead-shaped cross-linked polymer, polymethyl methacrylate (PMMA), polystyrene (PS), methyl methacrylate-butadiene-styrene (MBS), acrylonitrile-butadiene- As long as it is a polymer of any one or more crosslinked beads selected from styrene (ABS), methyl methacrylate-styrene (MS) resin, and the like, the present invention is not limited to the above-mentioned bead phase of the present invention, and it can scatter light. Crosslinked particles of any organic polymer can be used.

본 발명에서 상기 비드의 평균입경은 0.1 ~ 0.5㎛의 범위 내에서 사용하는 것이 바람직하며, 외부광을 적절하게 굴절시켜야 하기 때문에 0.1㎛ 미만으로 사용 하는 경우, 빛의 파장보다 작게 되어 빛이 굴절되지 않고 완전히 통과하고, 0.5㎛를 초과하는 경우, 표면이 매끄럽지 못하게 되므로 상기 범위 내에서 사용되는 것이 바람직하다. In the present invention, the average particle diameter of the bead is preferably used within the range of 0.1 ~ 0.5㎛, because the external light should be properly refracted when using less than 0.1㎛, light is less than the wavelength of light is not refracted If it passes completely without, and exceeds 0.5 μm, the surface is not smooth, it is preferably used within the above range.

그 사용량은 단량체에 대하여 0.5 ~ 3 중량부로 첨가되는데, 0.5중량부 이하로 사용되는 경우 광확산 기능이 떨어질 수 있으며, 3 중량부 이상으로 사용되는 경우 빛이 투과하지 못하여 광투과도가 떨어지며, 경제성도 낮아지므로 상기 범위를 사용하는 것이 바람직하다.The amount of the monomer is added in an amount of 0.5 to 3 parts by weight based on the monomer, and when used in an amount of 0.5 parts by weight or less, the light diffusing function may be degraded. It is preferable to use the above range because it becomes low.

이러한 확산제는 기재인 수지와의 굴절율 차이에 의해 광확산성을 높이는 역할을 하는 것으로, 고분자 주쇄에 가교되어 네트워크를 형성하므로, 본 발명의 광고판를 통과하는 빛은 가시광선이 없는 경우 여러 각도로 확산되어 다른 파장의 빛을 내게 된다. 따라서 주간에 가시광선에 의해 광고판를 반사해서 인간이 눈으로 볼 수 있는 색과 전혀 다른 색으로 조절하는 것이 가능하다. Such a diffusing agent serves to increase light diffusivity due to a difference in refractive index with a resin, which is a base material, and crosslinks to a polymer main chain to form a network, so that light passing through the billboard of the present invention diffuses at various angles when there is no visible light. And emit light of different wavelengths. Therefore, it is possible to reflect the billboard with visible light during the day and adjust it to a color that is completely different from the color visible to the human eye.

뿐만 아니라, 확산제로 사용되는 가교 고분자 미세분말을 색처리 하여 빛 투과시 원하는 색을 얻는 것도 가능하다. 예를 들어, 검은색염료를 사용하여 제조된 광고판에 백색 처리된 확산제를 사용하는 경우 주간에는 흑색 염료 자체의 칼라인 흑색으로 보이지만, 야간에 조명을 통과시키는 경우 가시광선의 반사에 의한 흑색은 보이지 않고 투과광에 의해 확산제에서 산란된 확산제의 칼라처리된 백색의 투과광만이 보여지므로 야간에는 백색으로 보이게 된다. 이러한 원리를 이용하여 간판에 적용하는 경우 주간과 야간에 다른색으로 보이게 된다.In addition, it is also possible to colorize the crosslinked polymer fine powder used as a diffusing agent to obtain a desired color when transmitting light. For example, if a white-diffused diffuser is used in a billboard made with black dye, it will appear black, which is the color of the black dye itself during the day, but if the light passes at night, the black due to the reflection of visible light is not seen. Instead, only the colored white transmitted light of the diffusing agent scattered from the diffusing agent by the transmitted light is seen, so that it appears white at night. When applied to a signboard using this principle, it will look different in day and night.

본 발명의 염료와 확산제는 중합단계에서 다른 조성물과 함께 투입하여 균일 하게 고분자의 매트릭스 내로 분산시키거나 또는 중합체를 제조한 후 컴파운딩에 의해 투입될 수도 있으나 본 발명에서는 제한되지 않는다. 다만, 중합 시 투입하는 것이 균일한 분산으로 더욱 선명한 색을 얻을 수 있게 된다.The dye and the diffusing agent of the present invention may be added together with other compositions in the polymerization step to uniformly disperse into the matrix of the polymer or by preparing a polymer and then compounding, but is not limited in the present invention. However, it is possible to obtain a more vivid color by the uniform dispersion during the polymerization.

본 발명에서 야간에 충분한 투과광을 확산하기 위하여는 사용한 광원의 세기를 높일수록 우수한 효과를 나타내므로 가능한 광원의 세기가 높을수록 우수하지만 통상적인 3파장 광원 또는 형광등의 광원 등으로도 본 발명의 목적을 달성할 수 있다.In the present invention, in order to diffuse sufficient transmitted light at night, the higher the intensity of the used light source shows an excellent effect, the higher the intensity of the possible light source is excellent, but the objective of the present invention is also used as a conventional three wavelength light source or a light source such as a fluorescent lamp. Can be achieved.

본 발명의 광고판은 압출 또는 사출에 의하여 제조할 수 있으나, 더욱 좋게는 케스팅 방법에 의하여 제조하는 것이 좋다. 본 발명에서는 판 형상 뿐만 아니라 시트, 성형체도 본 발명의 범주에 포함된다. 또한 본 발명은 광고용 간판 뿐만 아니라 조명이 사용되는 분야에는 제한없이 사용 가능하다.The billboard of the present invention may be manufactured by extrusion or injection, but more preferably by casting method. In the present invention, not only the plate shape but also the sheet and the molded product are included in the scope of the present invention. In addition, the present invention can be used without limitation in the field in which lighting is used as well as advertising signs.
