Conventionally, release paper with a squeeze pattern has been used in the production of dry synthetic leather and fake leather made from PVC paste, and in recent years, release paper with a squeeze pattern has been used in vacuum forming processes such as automobile crash pads. It has been used extensively in applications where vacuum forming is performed because the drawing pattern does not disappear during vacuum forming. However, all of the methods for producing these are the doctor knife method or the usual gravure printing method, and the products obtained have no distinctive features in terms of appearance.

The present invention aims to provide a synthetic resin sheet having an extremely excellent decorative effect in appearance for these uses.An example of its implementation will be explained with reference to the drawings. FIG. 5 is a step-by-step explanatory diagram showing a conventional manufacturing method; FIG. 8 is a schematic diagram of a printing device used in the present invention; FIG. Yes, this printing device is a variable speed printing device in which the rotational speed S1 of the metal printing roll 11 is about 2.5 to 3 times faster than the rotational speed S2 of the back-up rubber roll 12, and this device is used. This makes it possible to apply the printing ink 14 in accordance with the irregularities of the squeeze pattern formed on the release paper 1. Here, "according to the unevenness of the squeeze pattern" means that there are deep and shallow grooves, and deep grooves can hold a lot of printing ink depending on their depth, while shallow grooves can hold a lot of printing ink. , which means that it only takes a small amount of printing ink, which means that
This phenomenon occurs because the printing roll 11 rotates faster than the backup rubber roll 12 and therefore idles on the uneven patterned surface, ie, the printing ink 14 is scraped off. In contrast, conventional printing devices
In other words, if the rotational speed of the printing roll and the rotational speed of the backup rubber roll are the same, the depth of the recess will, in principle, change to the depth of Although it is possible to obtain a contrast between the concave and convex portions simply by applying printing ink, it is not possible to create a shadowy expression in which the concave portions are deep and shallow. However, in the present invention, the printing ink 14 in the ink pan 13 is applied to the printing roll 11 using this variable speed printing device by applying the drawing pattern surface of the release paper 1 which has been given a drawing pattern in advance, and using the back-up rubber roll 12 to ink the printing ink 14 in the ink tray 13. Print and apply. In this case, the printing roll 11 is used to apply the printing ink 14 over the entire surface of the release paper 1, and is not a printing roll with a special pattern, but a solid printing roll usually called a mesh roll. In this variable speed printing device, the ratio of the rotational speed S1 of the printing roll to the rotational speed S2 of the backup rubber roll is optimally in the range of S1 : S2 = 2 to 4:1, and S1 : S2. When the ratio of S 1 :S 2 is lower than 2:1, the effect of scraping off the printing ink is poor as in normal solid printing, so there is no step-by-step coating difference in the recesses, and the ratio of S 1 :S 2 is 4:1. If the ratio of S 1 :S 2 is in the range of 2 to 4:1, the rotational friction between the printing rolls of the shibori pattern becomes too large, causing other problems such as destruction of the shibori pattern. No drawbacks arise. That is, the release paper 1 is of a well-known form in this kind of technical field, and has a so-called squeeze pattern on its surface, which has a concave-convex pattern having deep concave concave portions 3, shallow concave concave portions 4, and convex portions 2. The printing ink 14 is printed on this squeezed pattern surface by a printing roll 11 of a variable speed printing device having a rotational speed of the above ratio. As a result of this printing, during concave drawing of the release paper 1, a relatively large amount of printing ink 5 enters the deep recesses 3, making the printing ink 5 dark, and only a small amount of printing ink 6 enters the shallow recesses 4, making it pale. In this case, the printing ink only adheres to the convex portions 2 of the squeeze pattern. Therefore, it is possible to obtain shading printing that corresponds to the depth and shallowness of the shibori pattern.

After performing shading printing on the release paper 1 in this way,
A synthetic resin layer 7 is laminated on the printed surface. In this case, the synthetic resin layer 7 can be laminated by various methods such as a coating method, a calender rolling lamination method, an extrusion lamination method, and a film lamination method, and the most common method is a coating method using paint. . When obtaining dry synthetic leather using this coating method, printing ink 1
4 is a printing ink prepared by adding an appropriate coloring pigment to a polyamino acid resin, a mixed solution of a polyamino acid resin and a polyurethane resin, or a two-component or one-component polyurethane solution, and the printing ink is applied to a release paper by the method described above. Apply to the squeezed pattern surface of No. 1 to obtain a shading print. Next, a coating layer made of a synthetic resin paint to become the synthetic resin layer 7 is applied thereon. In this case, the synthetic resin layer 7 may be a foamable layer. After the synthetic resin layer 7 is applied, an adhesive layer is applied and a base fabric is laminated to obtain synthetic leather. If the intermediate layer is a foam layer, prior to laminating the base fabric,
Alternatively, after lamination, the foam layer is foamed by placing it in a heating furnace, and after cooling, the release paper is peeled off.

The calender rolling/layering method is a manufacturing method suitable for mass production, and vinyl chloride resin is suitable for the synthetic resin layer 7. The vinyl chloride resin is not limited to soft vinyl chloride resins, and hard and semi-hard vinyl chloride resins can also be used. This is because the printed release paper can be laminated immediately after calender rolling, or in the case of a 4-roll calender, it can be laminated directly with the No. 4 roll. This is because the vinyl chloride resin is pushed in very easily. In the case of the calender lamination method, there is no need for post-processing of the vinyl chloride resin sheet, ie, processing such as printing or embossing. This is because this lamination process directly imparts the printing layer (and printing with shading) and the shibori pattern.

The extrusion lamination method and the film lamination method are also essentially similar to the calender rolling/lamination method. That is, it is only necessary to plasticize the synthetic resin layer 7 with heat and press the synthetic resin layer against the release paper 1 by applying a pressing force.

After the synthetic resin layer 7 is laminated in this manner, it is dried or cooled, and the release paper 1 is peeled off to obtain a synthetic resin sheet having a shading pattern that is in tune with the drawing pattern. Of course, the expression "sheet" means a sheet-like object, and as mentioned in the coating method, it also includes a structure in which a backing material such as a base fabric is laminated.

As mentioned above, the printing ink layer becomes thicker or thinner depending on the depth or shallowness of the concave aperture, but the thickness changes gradually, so when the synthetic resin layer 7 of a color lighter than the printing ink color is laminated, In the obtained product, the part corresponding to the deep concave part 3 and the high convex part 5 form a dark part, but the dark part also gradually becomes lighter from the center to the periphery or edges, and the concave part corresponding to the convex part 2 forms a dark part. 2' exhibits a color close to the color of the synthetic resin layer 7, and blends seamlessly with this color to form a very deep shading pattern. This phenomenon is caused by the fact that the low convex part 6 corresponding to the shallow concave part 4 exhibits a lighter color compared to the high convex part 5, but as above, the surrounding part or end part is confused with the concave part 2' corresponding to the convex part 2. Become one. Furthermore, when the color of the synthetic resin layer 7 is darker than the printing ink color, the high convex convex portions 5 corresponding to the deep concave portions 3 will be light colored, and the low convex convex portions 6 corresponding to the shallow concave portions 4 will be colored in the synthetic resin layer color. The color will become similar. Furthermore, if a synthetic resin layer 7 with a color completely different from the printing ink color is laminated, a sheet with different shading patterns in synchronization with the drawing pattern can be obtained.

In contrast, in the conventional method, the
As shown in the figure, since the printing ink enters so as to fill the entire concave diaphragm, there is a gap between the printing ink layer 8 corresponding to the deep concave diaphragm part 3 and the printing ink layer 9 corresponding to the shallow concave part 4. There is no difference in color, and only the convex portion 2 is slightly lighter colored. Therefore, even in a product in which the synthetic resin layer 10 is laminated and the release paper 1 is peeled off, the concave portions 2' corresponding to the convex portions 2 only exhibit the color of the synthetic resin layer 10, and the high convex portions corresponding to the deep concave portions 3 do not appear. No shading occurs between the portion 8 and the low convex portion 9 corresponding to the shallow concave portion 4. This is because the printing ink exhibits complete hiding properties when it reaches a certain thickness, and since the method of the present invention does not print shading according to the uneven aperture, the entire printed area ends up being the same color. becomes.
