Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a design paper that can be widely used for posters, calendars, indoor interiors, cosmetic containers, etc.

(B) Conventional technology Traditionally, transparent processed paper has been used for the window holes of envelopes so that the address printed on the envelope can be seen from the outside. It has been limited,
Design paper used for posters, calendars, indoor interiors, etc. has been designed using opaque printing such as primary color plates and offset printing, depending on the purpose.

(c) Problems to be Solved by the Invention Conventionally, transparent processed paper and design paper have completely different uses, and transparent processed paper has been used exclusively for industrial purposes.

The present invention aims to utilize the aesthetic aspects of transparent processed paper that have been overlooked so far, and to provide designed paper with unique aesthetic effects and designs that cannot be obtained with conventional offset printing.

(d) Means to solve the problem By partially applying transparent processing to the surface of the paper, which is the basic material, in an arbitrary shape according to the design plan, the transparent processed parts have a unique reflective effect on light. At the same time, the contrast with the opaque parts and the use of opaque ink to print from both sides of the material paper were used to create an unprecedented design effect.

(e) Effect of the invention After partially applying transparent processing to the paper surface of the basic material in an arbitrary shape according to the design plan, and printing from the front or back of the material paper with opaque ink as necessary. By performing transparent processing, the transparent processed part exhibits a unique reflection effect on light, and a striking contrast with the opaque or printed part can be obtained by the penetration effect of vision into the transparent part. The present invention will be described in detail according to the following.

The illustrated embodiment is an example of a design paper used as a poster, and 1 is high-quality paper as the basic material, and the surface 5 of the poster is printed with graphics 6 using ordinary opaque ink.
A, 6b and character printing 6C are applied, and the basic structure of the poster is formed by opaque printing. 3 is a transparent processing section, using as a transparent solution an ultraviolet curable coating resin prepared by using unsaturated polyester as the main ingredient and adding a vinyl monomer and a photosensitizing substance such as benzoin to this resin. Forming a coating film of the transparentizing solution in the shape of the plate surface where the paper surface is pressed on the back side 2 of the high-quality paper 1 which has finished the above-mentioned opaque printing by etc., and aiming to penetrate into the paper layer,
By irradiating the coating with ultraviolet rays, the coating portion is cured and polymerized, resulting in a transparent finish. In addition to the regular method using the above-mentioned printing plate, methods for forming transparent processed parts using a transparent solution include using a thermosetting resin such as a phenolic resin with a transparent solvent 4.
Alternatively, as shown in FIG. 3, a method may be employed in which the material is interposed and pressure-bonded between polymeric paper 1 serving as a basic material and then heat treated.

Note that in Examples 6a and 6b, the type of opaque ink was changed, but if 6a is printed from the back side 2 side and 6b is printed from the front side 5 side, the original opaque projection of the paper material part 7 and the transparent processed part You can get a unique effect with the dialogue of the transparent effect in 3.

As the transparentizing solution, a thermosetting resin such as phenol resin or urea resin may be used as in the case of the intervening solvent 4, but if heat treatment is not used, ultraviolet rays may be used in view of heat resistance and ease of writing and printing. It is more advantageous to use a curable resin.

By making the transparent processing part 3 transparent, the opaque print 6 printed on the poster surface 5 and the original paper part 7 stand out, and a unique aesthetic effect can be provided by contrast.

The above is an example of a poster, but for things that compete with lighting effects, such as indoor interiors, it is possible to further utilize effects such as reflection of lighting on transparent parts and backlighting.

(G) Effects of the Invention Since the present invention is constructed as described above, unlike the conventional designs using opaque printing such as primary color plates and offset printing,
By making full use of the aesthetic properties of transparent processed paper, which has a unique reflective effect on light and a penetrating visual effect, it is possible to create a unique design effect with a three-dimensional effect. The design effect can be enhanced by applying transparency to the whole or part of it.

The design paper obtained in this way can be widely used for posters, calendars, wrapping paper, envelopes, book covers, memo paper, stationery, etc., and can also be used for interior decoration such as hanging scrolls, shoji paper, wallpaper, etc. provide a use.
