JPS5969176A - Production of sheet colored in recessed part - Google Patents

Abstract

PURPOSE:To obtain a sheet colored only in the recessed part with ease, by incorporating silicone only on the surface in the projecting part of a sheetlike base material having ruggedness on the surface then applying a coloring material over the entire part of the surface. CONSTITUTION:A sheetlike base material (for example, polymer of vinyl chloride-, vinyl chloride-vinyl acetate-, ethylene-vinyl acetate-base) having ruggedness on the surface is prepared. Transparent ink contg. silicone is applied only on the surface in the projecting part of such base material. A coloring material is then applied over the entire part of the surface of the base material. The surface in the projecting part is kept free from sticking of the coloring material by the effect of silicone and only the recessed part is colored by the above- mentioned method.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for easily producing a sort with colored recesses.

Conventionally, methods for coloring only the concave portions of a sort with an uneven surface include an embossing method in which coloring is applied at the same time as embossing, and a method in which the coloring material is applied to the entire surface and the coloring material applied to areas other than the concave portions is wiped off. However, these methods have problems with equipment, workability, stability, etc., and have not been able to stably produce inexpensive colored sorting.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and is intended to color the concave portions of a sorted substrate having an uneven surface by a simple method such as printing.

The present invention will be described in detail below with reference to the drawings.

First, as shown in Fig. 1, a transparent ink (3) containing lincone is applied only to the surface of the convex part (2) of a sorted base material (it) having an uneven surface. By reducing the printing pressure to around 0.51-ton (linear pressure) and using an impression cylinder with a high surface hardness (for example, 80 to 90 degrees), it is possible to easily apply transparent ink only to the surface of the convex part. You can do it.

Next, when coloring material (4) is applied to the entire surface, convex parts (2)
The coloring material (4) does not adhere to the surface due to the action of the silicone in the transparent ink (3), and therefore the coloring material (4) is applied only to the recesses (5) as shown in FIG. The method of applying the coloring material may be a printing method or a coating method using Coke.

Next, each of the 42 materials used in the present invention will be explained.

As the sorted substrate (1), films made of vinyl chloride, vinyl chloride/vinyl acetate, ethylene vinyl acetate, or other resins can be used, and if necessary, asbestos paper, nonwoven fabric, or glass sorting can be used on the back side. , metal foil, wallpaper lining paper (Kenjin WK-8ONX, 80AF-10)
) can also be laminated with a backing material such as

The transparent ink (3) containing polymericone and the coloring agent (4) applied thereon include inks and paints based on resins such as vinyl chloride, vinyl chloride vinyl acetate, urethane, and acrylic. You can use it.

The method of the present invention comprising the steps described above has the following effects.

■It does not require special equipment such as wiping equipment, and can be performed using only a printing machine, coater, etc.

■Uses less ink than the wiping method.

■The convex portions are coated with ink containing lilac, making them difficult to get dirty at ℃ or 100 degrees.

Next, examples will be shown.

(Example) A wallpaper lining paper was coated with a vinyl chloride paste of the following composition to a thickness of 0.2 M using a knife coater, heated to gel, and then embossed.

1) Next, a resin made mainly of vinyl chloride vinyl acetate resin and acrylic resin was used.
Using ink containing 5% of P-357), the rubber hardness of the impression roll was increased to 90' using a gravure printing machine.
, Print with a printing pressure of 0.5) so that the ink sticks only to the embossed convex parts, and dry. Next, use brown ink for vinyl chloride and print on an impression roll with a rubber hardness of 70. Printing was carried out under the condition of 2 tons, and only the concave portions were colored to obtain a concave colored sort.

[Brief explanation of drawings]

The drawings show examples of the method of the present invention, in which Fig. 1 shows a state in which a transparent ink containing 7 recone is applied only to the surface of the convex portions of a sheet-like substrate, and Fig. 2 shows a state in which a transparent ink containing 7 recone is applied only to the convex portions of a sheet-like substrate, and Fig. 2 shows a state in which a coloring agent is applied only to the concave portions of a sheet-like substrate. FIG. 4 is a cross-sectional view showing the applied state. (1)... Sorted base material (2)... Convex portion (3)
