Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed matter in which printed patterns hidden in the lower layer can be easily revealed by removing the opaque coating layer by scratching or the like.

A printed matter in which a hidden design can be revealed by scratching, etc. has already been published in 15842, for example, but in this invention, opaque printing is performed directly on the design printed using ink mixed with wax. It forms a layer, and its characteristic is that the affinity between the pattern printing ink and the opaque printing layer ink is lowered by wax, but when removing the opaque printing layer by rubbing, etc., the amount of force applied and Depending on the utensil used, the pattern may be damaged or the ink from the opaque printing layer may be mixed into the pattern, making the pattern unclear.

Furthermore, there is a problem in that the opaque printing layer, which is designed to fall off with a relatively weak force such as being squeezed, may be damaged before use due to shifting of the load during the distribution stage.

This invention solves the above problems,
The features are that the opaque coating layer that hides the pattern printing layer provided on the base sheet is made of a composition containing polybutene resin, and the adhesive layer is percoated to make it removable as a transparent protective film. This is to protect the opaque coating layer from unnecessary physical sliding pressure as much as possible.

The embodiments shown in the drawings will be explained below.

FIG. 1 is a sectional view of a main part showing an embodiment of the present invention, in which 1 is a base sheet of paper or plastic, etc.;
2 is a pattern printing layer printed on the base sheet 1. Offset printing, flexographic printing and gravure printing are suitable for printing the pattern printing layer 2 on the substrate 1.

Reference numeral 3 denotes an opaque coating layer that hides a necessary portion of the pattern printing layer 2, and is formed by offset printing, gravure printing, flexographic printing, and silk printing.

Reference numeral 4 denotes a part-coated adhesive layer having adhesive properties provided on the part of the pattern printing layer where the opaque coating layer is not applied, and allows the transparent protective film 5 that non-adhesively covers the opaque coating layer 3 to be peeled off. It is kept attached.

The transparent protective film 5 protects the opaque coating layer 3 until the actual printed matter is used, and reduces and protects the unnecessary external forces such as friction applied during the distribution stage as much as possible. Even if the coating layer 3 were to peel off or fall off, it would remain within the transparent protective film 5 without being dissipated, and would not cause sanitary problems, for example, when the coating layer 3 is stored together with food.

FIG. 2 is a sectional view showing a state in which a part 3' of the more opaque coating layer 3, such as a hitch, has been removed from the original printed matter with the transparent protective film 5 removed, and the pattern printing layer hidden in the lower layer of this part. 2 is manifesting.

In the above-mentioned present invention, the opaque coating layer 3 is formed by, for example, gravure printing, flexographic printing, or silk printing, and silk printing using synthetic rubber resin can provide high opacity.

Therefore, in the present invention, when forming the above-mentioned opaque coating layer 3, polybutene resin, 0.550
% (solid content), which makes it easy to remove by rubbing etc., and in particular prevents it from becoming difficult to peel off due to changes over time, so that it can be used for a long period of time. It has sufficient resistance to circulation and can be easily peeled off.

For example, even if it is stored at a temperature of 30°C or higher for a long period of time, it will not peel off due to scratches or the like.

In the above, the polybutene resin may be a known one, such as a crystalline high molecular weight isotactic structure obtained by polymerizing butene-1.

In addition, in the present invention, the above composition includes:
Using ordinary ink or paint vehicle as a component, coloring agents such as pigments, etc. are added to this,
A composition prepared by sufficiently kneading with a solvent, diluent, etc. can be used, and a composition containing a polybutene resin can be used.

The amount added is preferably 0.5 to 50% by weight in terms of solid content; if it is less than 0.5% by weight, it will not have the effect, and if it is more than 50% by weight, it cannot be mixed into the ink or coating composition. It is not desirable.

Next, in the above-mentioned present invention, the adhesive layer may be, for example, vinyl acetate resin-based, synthetic rubber-based,
It is formed by part coating using vinyl chloride resin, polyester resin, polyethylene wax, etc., and the transparent protective film 5 is attached to the adhesive part coat adhesive layer 4 to the extent that it can be easily peeled off.

As the transparent protective film 5, for example, a polypropylene film is suitable, but a biaxially stretched film is particularly suitable from the viewpoint of wrinkle generation and film cutting. Polyethylene films are also suitable.

The printed material of this invention has the structure, function, and effect described above, and is highly practical as it can be used as a lottery ticket as shown in the perspective view of FIG. 3, as well as toys and prizes for school children.
