Abstract

(57) [Problem] To provide a decorative sticking paper which is easy to produce, has a natural visual effect, and is excellent in a three-dimensional effect. SOLUTION: As a manufacturing method of this decorative sticking paper, first, a single-layer release agent 2 is printed on a paper material 1 to obtain a bottom-layer paper. Next, an adhesive having the same outline as the predetermined design is printed on the paper of the bottom layer to form the adhesive layer 3. Subsequently, a resin having the same contour as that of the predetermined design is printed on the adhesive layer 3 to form the printing plate layer 4 and then heat-treated. Then, a large number of predetermined designs are printed on the printing plate layer 4 at a time by a technique called flat plate printing to form a multicolored colored print.
After that, a single-layer protective film 5 is printed on the multicolored colored print drawing and heat-treated to complete a decorative sticking paper.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sticking paper for decoration.

[0002]

[Prior art]

 As is well known, the technique of screen printing conventionally prints a pattern and a color on a printing plate layer.

[0003]

[Problems to be solved by the invention]

 However, when printing by the above-described method, only one type can be printed in a predetermined design area local area. Once overprinted, it must be dried once, so if a design has five or more colors, it must be overprinted and dried five or more times. As a result, it takes much time and the production efficiency deteriorates. In the worst case, halftone printing technology prints one color at a time in the local area of the design area, so when all colors are printed, there will be parts that stand out in adjacent positions of different colors, However, not only the overall visual effect is not natural, but also the three-dimensional effect is deteriorated.

Accordingly, an object of the present invention is to provide a decorative sticking paper which is easy to manufacture, has a natural visual effect, and is excellent in a three-dimensional effect.

[0005]

[Means for Solving the Problems]

 As a decorative sticking paper of the present invention to achieve the above-mentioned object, first, a single-layer release agent is printed on a paper material to form a bottom-layer paper. Next, an adhesive having the same contour as the predetermined design is printed on the paper of the bottom layer to form an adhesive layer. Subsequently, a resin having the same contour as that of the predetermined design is printed on the adhesive layer, and after the printing plate layer is formed, heat treatment is performed. Then, a large number of predetermined designs are printed on the printing plate layer at a time by a technique of flat printing, thereby forming a multicolored colored print. After that, a single-layer protective film is printed on the multi-colored colored print drawing, and heat treatment completes the decorative sticking paper.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The decorative sticking paper according to one embodiment of the present invention is manufactured as shown in FIG. 1, has the structure shown in FIG. 3, and forms the appearance as shown in FIG. The manufacturing method is as follows. (1) A single-layer release agent 2 is printed on a paper material 1 to obtain a bottom-layer paper. In this embodiment, a polyvinyl alcohol (PVA) material is used for the release agent 2.

(2) The adhesive layer 3 is formed by printing an adhesive having the same outline as that of the predetermined pattern on the paper of the bottom layer by the technique of halftone printing. Generally speaking, the adhesive is formed from an oily or water-based material (eg, a polymer such as an acrylic resin), but a water-based adhesive is often used. This is because when the adhesive paper is peeled off after a certain period of use, the adhesive remaining on the article can be easily removed.

[0008] (3) By using a halftone printing technique, a resin having the same outline as that of a predetermined pattern is printed on the adhesive layer 3 in the step (2) to form the printing plate layer 4. (4) By performing heat treatment on the paper, adhesive layer, and printing plate layer as the bottom layer in step (3), an excellent bonding force is formed between the adhesive layer and the printing plate layer. The temperature range of the heat treatment is 170 ° C. to 190 ° C., and the heating time is 5 minutes.

(5) A large number of predetermined designs are printed on the printing plate layer of step (4) at a time by a technique of lithographic printing, thereby forming a multicolored colored print drawing. (6) Using a technique called halftone printing, a single-layer protective film 5 is printed on the multicolored color-printed drawing of step (5). In this embodiment, a polyurethane (PU) material is used for the protective film 5.

(7) When the paper, the adhesive layer, the printing plate layer, the multicolor layer, and the protective film of the bottom layer in the step (6) are subjected to a heat treatment, a decorative adhesive paper is completed. The temperature range of the heat treatment is 170 ° C. to 190 ° C., and the heating time is 5 minutes.
