DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention diffuses reflected light from advertisements, hanging drawings, hanging tables, hanging scrolls, reproductions, explanatory drawings for educational materials, etc. (collectively displayed as posters in the present specification), and provides anti-glare properties. The present invention relates to a method for manufacturing a given non-glare poster.

[0002]

2. Description of the Related Art Conventional posters are generally provided with a smooth and glossy surface finish in order to enhance image effects such as sharpness, volume, and density. On the other hand, the visual field is obstructed by the reflected light reflected in the symmetrical direction depending on the viewing position, and there is a range invisible to the naked eye. In recent years, non-glare posters having a non-glare layer having irregularities on the poster surface have come to be seen in order to diffuse such reflected light from the poster so that it can be seen from any position.

Further, since the non-glare layer of the non-glare poster is usually formed with uniform unevenness, for example, the back of the shadow portion of the picture does not have the color unevenness of the ink composed of the halftone dots, and the beautiful tone can be reproduced. However, in a highlight portion such as a face portion of a person, there is a drawback that the skin becomes rough due to the unevenness of the non-glare layer. In order to solve such defects, it is possible to partially diffuse the reflected light by changing the size and density of the unevenness of the non-glare layer according to the highlight part and shadow part of the picture, it is possible to solve it is there.

[0004]

However, when manufacturing a non-glare poster, it is necessary to attach a non-glare sheet to the surface of the poster using an adhesive, and color change such as yellowing generated in the adhesive is required. In addition, air is trapped between the target surface and the non-glare sheet at the time of bonding, an air layer remains, and the normal image often looks distorted, so it is necessary to pay close attention to the bonding of the non-glare sheet there were. An object of the present invention is to provide a method for easily and inexpensively manufacturing a high-quality non-glare poster in which a non-glare layer is integrally formed without using an adhesive and leaving an air layer on the poster surface.

Further, it is difficult to partially adjust the size or density of the uneven surface of the mold according to the pattern of the non-glare layer, the cost is high, and the practicality is poor.
Little was implemented. The present invention also solves such a problem, and partially forms a non-glare layer, or partially forms unevenness of the non-glare layer, and partially forms the unevenness of the non-glare layer, so that a high-quality non-glare poster that can emphasize the tone peculiar to a pattern is provided. Is also provided.

[0008]

As the transparent film of the thermoplastic synthetic resin used in the present invention, an ethylene / vinyl acetate copolymer (EV
A) A transparent film of resin, polystyrene, polyethylene, PVC, ionomer, EAA, polyamide, etc. can be used, but a transparent film of EVA resin having good transparency, good moldability, low cost and high water resistance is particularly effective. And the thickness is 10 to 500 μm and 30 to 120 μm.
m is preferred.

Then, as shown in FIG. 1, a transparent film 1 of a thermoplastic synthetic resin is placed on the surface of the paper 3 on which the picture 2 is printed, and the temperature is about 0.5 to 2 kgf under a temperature condition of about 40 to 60 ° C.
/ Cm ^{2 at} the pressing pressure of the former stage, and then the hot pressing at the heating pressing pressure of 10 to 30 kgf / cm ² for about 60 to 150 seconds.
It is effective to evacuate the air entrapped between the sheet and the sheet 3 and temporarily bond the sheet and the film. The deaeration during the temporary lamination can be completely performed by the low-temperature front-back heating press.

Next, the embossed concavo-convex mold 4 is superimposed on the transparent film 1 obtained by temporarily laminating the paper and the film, and from both sides of the embossed concavo-convex molds, the pad is pressed with a hot plate 5.5 at a temperature of 90 to 130.degree. Pressure 10-30kgf / cm
² is performed for about 60 to 150 seconds to melt and soften the transparent film 1, perform non-glare processing by the embossing concave and convex mold 4, and simultaneously perform the actual bonding to the paper 3, as shown in FIG. A non-glare poster having the non-glare layer 7 is obtained. The embossed unevenness has an acute angle in part, and has a reverse taper part in the middle part,
It is preferable that the height distribution and the shape of the unevenness are not uniform, the distribution density is 30 to 1000 mesh, preferably 80 to 300 mesh, and the distribution density is changed in the above range, or by changing the uneven shape. For example, a three-dimensional effect of a picture printed with a screen ruling of 150 L,
It is possible to control the expression such as tone.

As the embossed concave / convex mold 4, a mold such as silicone rubber, PP, unsaturated polyester resin, diallyl phthalate (DAP) resin, phenol resin, epoxy resin, PET, or a mold can be used. Silicone rubber is excellent. Silicone rubber is
It is excellent in heat resistance, easy to make fine irregularities, and excellent in releasability from the transparent film for molding during non-glare processing. For example, abrasive grains such as alundum and carborundum are dispersed and fixed on a base material such as plywood or a metal plate, and liquid silicone rubber is injected from above or pressed against a plate-like silicone rubber. , Make a female mold in which minute irregularities of the shaping manuscript are dug. By using a silicone rubber female mold as the embossing irregularity mold 4 as described above, the mold can be separated by elasticity even if irregularities having a reverse taper are formed, and the reverse taper of the non-glare layer 7 as shown in FIG. Since the irregularities with the portions can reflect the incident light also in the incident direction, the effect of diffusing the reflected light becomes large.

Further, in the non-glare poster manufactured by the present invention in which the diffusion of the reflected light is partially changed, for example, a partially transparent non-glare layer 7 is formed on the picture 2 printed on the paper 3 in FIG. In FIG. 5, the non-glare layer 7 is partially formed in the gross portion 8 by hot pressing, and FIG. 6 shows the unevenness of the non-glare layer 7 partially in the rough portion 9 and the dense portion 10. It is formed by changing. The thickness of the non-glare layer 7 is 10 to 500 μm, the density of the unevenness is 30 to 1000 mesh, and the shape of the unevenness is discontinuous in both distribution, height, and shape. In such a non-glare poster, the tone unique to the pattern can be emphasized by changing the glare degree of the highlight portion and the shadow portion and partially changing the diffusion of the reflected light of the pattern.

Example 1 A sheep pattern was printed by offset printing on 110 kg of SK coated 46-sheet SK coat made by Sanyo Kokusaku Pulp. An EVA resin transparent film having a thickness of 60 μm is overlaid on the surface of the printed paper, and a pre-press pressure of 1.0 kgf / cm is applied at a temperature of 50 ° C.
^{2. A} low-temperature heat press was performed for 90 seconds at a post-stage press pressure of 20 kgf / cm ² , and air trapped between the paper and the transparent film was degassed to perform temporary bonding. Next, a silicone rubber embossed concavo-convex shape having an acute angle portion, and irregularities including a reverse tapered shape having irregular shapes, distribution densities, and heights formed in 120 mesh. The mold is superimposed on the temporarily bonded transparent film and subjected to a high-temperature heating press at a temperature of 110 ° C. and a pressure of 20 kgf / cm ² for 90 seconds to melt and soften the transparent film to perform non-glare processing, and at the same time to form a paper. This book was pasted. When the reflected light of the two types of non-glare-processed and non-glare-processed non-glare-processed patterns was measured in this way, the results shown in Table 1 were obtained.

That is, not only does the non-glare treatment prevent the obstruction of the visual field due to the reflected light, but also the non-glare-treated picture and printing paper have excellent water resistance and do not have a color change such as yellowing because no adhesive layer is provided. In addition, the use of an EVA resin film enables expression of a wet color that cannot be expressed by printing.

Example 2 A 60 μm thick transparent film 1 of a thermoplastic synthetic resin such as EVA resin or PVC was cut into a shape obtained by a scanner and a photographic means at a shadow portion of a picture pattern on a sheet of paper. The transparent film 1 is overlaid on the paper 3 on which the picture 2 is printed as shown in FIG. At a temperature that does not cause thermal deformation (about 40-60 ° C),
The paper 3 and the film 1 are temporarily bonded by a low-temperature heating press with press pressure (press pressure of 10 to 30 kgf / cm ² ). The low-temperature heating press for this temporary bonding is divided into two stages, and the pressure of the subsequent stage is set higher than the pressure of the previous stage. Next, after the embossing concave and convex mold 4 is overlaid on the film 1, press-pressing (10 to 3) at a heating press temperature (90 to 130 ° C.) at which the film 1 melts and softens.
0 kgf / cm ² ), a non-glare layer was formed on the film 1 by a high-temperature heating press under the conditions of maintaining the non-glare layer on the film 1, and a non-glare poster partially formed with the non-glare layer was obtained.

Example 3 A plate for silk screen printing of a portion necessary for a picture is prepared by photographic means, and a transparent resin of a thermoplastic resin such as an EVA resin or an olefin resin, and if necessary, a foaming material is added. After printing by the silk screen printing method, the printed portion is formed into a non-glare layer by a heat press under a condition of press pressure (10 to 30 kgf / cm ² ) at a heat press temperature (90 to 130 ° C.), A non-glare poster in which a non-glare layer was partially formed was obtained.

Example 4 In Example 1, a transparent film was superimposed on the surface of the paper on which the picture was printed without cutting, and a non-glare layer was formed on the entire surface of the paper by a hot press. Is superimposed on the non-glare layer using a mold having a convex shape, and heated and pressed again at a temperature of 90 to 130 ° C. and a pressure of 10 to 30 kgf / cm ² to partially form a gloss portion. A matte non-glare poster was obtained.

Example 5 A transparent film of a thermosetting synthetic resin was overlaid on the entire surface of a paper on which a picture was printed, and heated and pressed to form a non-glare layer. Then, a desired portion was further partially cut on the non-glare layer. A transparent film of thermoplastic synthetic resin was overlaid, and by hot pressing, non-glare processing and lamination were performed in a form having unevenness with a different density from the previously formed non-glare layer on this transparent film, and the density of the unevenness was partially changed. Non-glare posters with different glare degrees, in which coarse and dense portions are mixed, were obtained.
