DETAILED DESCRIPTION OF THE INVENTION

 Purpose of the invention

[Industrial applications]

The present invention relates to a method for producing a decorative screen having different patterns on the front and back sides, and through which the opposite side is visible.

[Prior art]

Called "dual screens" or "dual stickers", decorative screens having different patterns on the front and back are used. As a technique for manufacturing this, a method of printing a picture on both sides of an opaque base material, or providing a base layer of white or another color in a printing area of a transparent base material and printing a pattern on both sides thereof is provided. is there. It is often desirable for this type of decorative screen to be able to see through behind what is behind it, for which purpose it is possible to provide a large number of through-holes, or to form a dot-shaped or matrix-shaped unprinted part on a transparent substrate. Or to provide.

[Problems to be solved by the invention]

The object of the present invention is to have different patterns on each side,
In addition, it is an object of the present invention to provide a manufacturing method capable of obtaining two types of decorative screens from a single manufacturing process cycle in the manufacture of a decorative screen that can be seen through in both directions. Structure of the invention

[Means for solving the problems]

The method for manufacturing a see-through decorative screen of the present invention comprises the following steps as shown in FIGS.
That is, first, as shown in FIG. 1, a perforated film 2 having a large number of dot-shaped holes formed in a second transparent base material is temporarily bonded on a first transparent base material 1, As shown in the figure, a first pattern printing layer 3, a concealing layer 4, and a second pattern printing layer 5 are provided in this order on the first and second base materials, except that the first and second patterns are provided. In each of the patterns of the above, one pattern is formed only by the above-mentioned dot area, and one pattern is formed only by the other areas of the matrix. Then, as shown in FIG. Then, the perforated film 2 is peeled off, and a dot-shaped pattern is printed on the first transparent substrate 1 as shown in the upper part of FIG.
And a first decorative screen having a different pattern print 5A and having a matrix-like light-transmitting portion 6, and at the same time, a matrix-like pattern on the perforated film 2 as shown in the lower part of FIG. To obtain a second decorative screen having the pattern printing 3B, the concealing layer 4B, and the pattern printing 5B, and having the light-transmitting portion 7 which is a dot-shaped hole. As the first transparent substrate, any material selected from a sheet of plastic such as polyester, polycarbonate, and rigid polyvinyl chloride can be used arbitrarily. The selection of the ink and the printing method may be in accordance with known techniques. The shape of the dot is not limited to a circle, but a triangle, square, hexagon,
Arbitrary such as a star. As the film material used as the second transparent substrate, plastics such as polypropylene and polyethylene are suitable. The dot holes are provided by means such as a punch press. Although the size and distribution of the holes are arbitrary, it is preferable to increase the number of small-diameter holes because they do not impair the pattern and are easy to see through.

[Operation]

According to the production method of the present invention, printing of a dot-shaped pattern on the first transparent base material, having a masking layer on both sides thereof, with a concealing layer therebetween, and having a matrix-like light-transmitting portion, ,
At the same time that a positive see-through decorative screen is obtained, a matrix-shaped pattern is printed on a perforated film, which is a second transparent substrate, again with a masking layer on both sides, And having a light-transmitting portion that is a dot-shaped hole,
As a result, a negative type see-through decorative screen can be obtained at once.

【Example】

The polypropylene film temporarily bonded on the mount was half-cut in a circular dot shape using a die, and the polypropylene film was peeled from the mount to prepare a perforated polypropylene film. The above-mentioned perforated polypropylene film is temporarily bonded on a 100 μm thick polyester film, and the first pattern is printed on the polyester film by silk-screen printing using three colors of red, yellow and blue inks of polyester resin. Was printed.
Subsequently, a concealing layer was formed by silk-screen printing using also two colors of polyester resin white and silver inks. Further, a second pattern was printed on the above-mentioned concealing layer using a three-color ink of a polyester resin-based brown, black and blue. Next, the perforated polypropylene film was peeled off from the polyester film to obtain two types of decorative screens as shown in FIG. 3, in which the pattern portion and the light-transmitting portion had a positive and negative relationship with each other. The inks used contained the following pigments, respectively, 20% polyester resin, 1% surfactant
The other is a solvent (MEK / anone mixed solvent). Red: Watching Red 15% Yellow: Disazo Yellow 8% Blue: Cyanine Blue 8% White: Titanium White 15% Silver: Aluminum Paste 10% Black: carbon black 5% Effect of the Invention According to the method for producing a see-through decorative screen of the present invention, a decorative screen that has different patterns on the front and back, and that can be seen through in both directions, is produced at one time. You can get two at once in a cycle. The resulting see-through decorative screen is useful when used for transparent doors and partition panels in houses and offices. It is also effective when used for a display in a store. For use, for example, a transparent pressure-sensitive adhesive or adhesive may be applied to the back surface and directly adhered, or another transparent substrate may be laminated on the printed surface as a protective layer and then adhered.
