Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern-printing masking sheet for easily and clearly printing a design on an article such as cloth, and a design printing method using the masking sheet. is there. Incidentally, the pattern-printing masking sheet referred to in the present invention means that when a pattern such as characters is printed on an article, a sheet having the pattern cut is attached to the surface of the article, and the coating is applied only to the portion not covered by the sheet. Is applied, and then the sheet covering the article surface is peeled off, and a portion which covers the article surface with the sheet and is not colored,
It is used to make the outline of the portion to be colored stand out.

2. Description of the Related Art Conventionally, a masking sheet has been widely used as a method for printing a design on the surface of a small lot of articles. In this method, a predetermined pattern is cut into a material such as paper, attached to the surface of an article, a coating is applied only to a portion not covered by the masking sheet, the coating is dried, and then the masking sheet is removed. This is a simple means. However, in this method, when there is a discontinuous part in the design after cutting, only this part needs to be attached to the surface of the article separately from other parts, so the position of the design is likely to shift There was a problem.
Also, there is a method of manually writing the design, but it has a problem that skilled technique and labor are required. On the other hand, a roller printing method, a screen printing method and the like have been used as a method for printing a design on a fabric. In these methods, it was necessary to replace the engraving roller, the screen, etc. every time the design was changed. Further, there is a problem that it is economically unfeasible unless a lot production amount is considerable, because the engraving roller, the screen and the like are expensive to produce.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and can economically deal with pattern printing on a small lot of articles, and can make clear prints. It is an object of the present invention to provide a pattern-printing masking sheet for printing on a mask and a method for printing a pattern on an article using the masking sheet.

【Example】

[Example 1] 100 μm thick as a heat-resistant sheet for the first layer
Polyethylene terephthalate sheet was used as a base material, and polypropylene as a second-layer base material sheet was laminated on the polyethylene terephthalate sheet using an extrusion laminating machine so as to have a thickness of 100 μm. Thereafter, similarly, using an extrusion laminating machine, a low-density polyethylene resin was laminated as a thermoplastic resin layer of the third layer on the polypropylene layer which is the base sheet of the second layer so that the thickness thereof was 10 μm, A transparent pattern-printing masking sheet having a thickness composition of terephthalate / polypropylene / low-density polyethylene of 100/100/10 μm was obtained.

Further, the above-mentioned masking sheet for pattern printing was cut with a cutting machine manufactured by Muto Kogyo Co., Ltd. to cut the letters "Great sale" except for the first layer of polyethylene terephthalate. Then, the polypropylene layer as the second layer and the low-density polyethylene resin layer as the third layer were peeled off and removed, leaving only the coloring unnecessary portion on the article. Then, the low-density polyethylene resin layer, which is the third layer of the masking sheet, was brought into contact with a cotton curtain,
The polyethylene terephthalate layer side of the first layer was thermocompression bonded with an iron having a surface temperature of 150 ° C. Next, the polyethylene terephthalate layer of the first layer was peeled and removed, and a red paint was sprayed on the portion not covering the article to color the article. Then, after the paint was dried, the polypropylene layer of the second layer and the low-density polyethylene resin layer of the third layer covering the article were removed. The obtained hanging screen had a clear print finish with the outline of the characters prominent. Further, since the masking sheet had transparency, the work of aligning it by contacting it with the hanging curtain was easy.

Example 2 A polyethylene terephthalate sheet having a thickness of 100 μm was used as a heat-resistant sheet for the first layer, a polycarbonate sheet having a thickness of 50 μm was used as a substrate sheet for the second layer, and a first layer was formed using a dry laminating machine. A layer of polyethylene terephthalate sheet and a second layer of polycarbonate sheet were laminated. The lamination was performed by applying a urethane adhesive on the polyethylene phthalate sheet in an amount of 2 g / m ^{2 in} terms of solid content weight, drying the solvent, and then laminating the sheet onto a polycarbonate sheet. Then, using an extrusion laminating machine, the third layer of low-density polyethylene resin is laminated on the second-layer polycarbonate so that the thickness thereof becomes 10 μm, and the thickness of polyethylene terephthalate / adhesive / polycarbonate / low-density polyethylene resin is laminated. Structure is 100/2/50/1
A transparent pattern-printing masking sheet having a thickness of 0 μm was obtained. Using the obtained pattern-printing masking sheet, a hanging curtain was printed in the same manner as in Example 1. As a result, as in the case of Example 1, the outline of the character was conspicuous and the print finish was clear. Further, since the masking sheet had transparency, the work of aligning it by contacting it with the hanging curtain was easy.

Example 3 A polyethylene terephthalate sheet having a thickness of 100 μm was used as the heat-resistant sheet of the first layer, and a kraft paper sheet having a thickness of 90 μm was used as the base sheet of the second layer, and the polyethylene of the first layer was formed using an extrusion laminating machine. The terephthalate sheet and the second layer of kraft paper were laminated by using low density polyethylene as a binder. The thickness of the polyethylene layer used as the binder was 5 μm. After that, further using an extrusion laminating machine, a third layer of low-density polyethylene resin was laminated on the second layer of kraft paper so that the thickness was 10 μm,
Thickness composition of polyethylene terephthalate / low density polyethylene / kraft paper / low density polyethylene resin is 100
A masking sheet for pattern printing having a thickness of / 5/90/10 μm was obtained. By using the obtained pattern-printing masking sheet, a hanging curtain was printed in the same manner as in Examples 1 and 2. As a result, as in Examples 1 and 2, the outline of the character was conspicuous and the print finish was clear.
