Field of the Invention The present invention relates to a method for producing a sheet-like material such as vinyl chloride wallpaper or vinyl chloride leather, in which different concave and convex patterns are formed on the surface and pattern deviation does not occur at the boundary of the concave and convex patterns.

った。2. Description of the Related Art Conventionally, a vinyl chloride wallpaper or vinyl chloride leather product with an uneven pattern, which is called a synchronous product, has an appropriate pattern printed on the sheet surface, and then the printed portion is textured with an embossing roll. , The concavo-convex pattern is highlighted by synchronizing the printed pattern and the embossed pattern. This type of embossing roll is made so that the pattern repeat is narrowed in consideration of shrinking the base due to graining, but the base expands and contracts due to heating conditions and the pressing force of the embossing roll. Therefore, in actual work, a skilled worker always monitors visually, and if there is a deviation, various factors of variation were finely adjusted and synchronized according to conventional experience, so there is no certainty and quality , Yield didn't come to my mind.

However, various fluctuation factors such as heat quantity, tension, pressure, etc. can be comprehensively controlled to appropriately respond to slight changes in conditions. Since it was not a thing, even if it was automated, in the end it was necessary to make visual adjustments by the above-mentioned skilled workers.

ことによって、上記の目的を達成したものである。According to the present invention, a desired pattern is printed on a vinyl chloride base containing a foaming agent with a foam promoting ink, and the foam promoting ink is a different foam promoting ink having a different foam rise time. By printing a desired pattern on the above pattern and then heat-foaming it, the foaming agent-containing vinyl chloride base at the position where the patterns overlap is used to accelerate foaming in the foaming promoting ink. The above object is achieved by exposing a foamed pattern by the ink and canceling the pattern by the foaming promoting ink having a slow foaming rise time.

の境目で歴然と区別されることになる。[Working] When a vinyl chloride base containing a foaming agent is heated and foamed by partially or completely overlapping the printed pattern of the foam promoting ink with a fast foam rise time and the printed pattern of the foam promoting ink with a slow foam rise time, Regardless of which ink is on top or bottom, regardless of that, when the foaming agent contained in the base is thermally decomposed and gasified, and bubbles are formed to bulge the handle, the foam rise time is increased. When the accelerator in the early foaming ink works preferentially and the later accelerator becomes effective, the foaming agent that should create bubbles is gone, so the patterns overlap when printing. However, after foaming, only the pattern made by the foaming promotion ink with a fast foaming rise time is exposed, and the pattern made by the foaming promotion ink with a slow foam rise time is canceled out. Will be done.

を製造することができる点で甚だ優れている。As described above, according to the present invention, the foaming accelerating inks printed on the vinyl chloride base containing a foaming agent have different foaming rise times, and the patterns drawn by the inks are printed so as to overlap each other. As a result, after foaming by heating, only the foamed pattern of foamable ink with a fast foaming rise time is exposed, and the foamed pattern of foamable ink with a slow foam rise time is canceled, so there is no pattern shift and it is superior to the conventional synchronized product. It is extremely excellent in that it is possible to produce a sheet-like article having an uneven pattern which is not inferior.
