DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an image of a continuous pattern with an adhesive on a material to be transferred by combining various printing means and pressure transfer means.

[0002]

2. Description of the Related Art Conventionally, as a method of forming an image of a continuous pattern with an adhesive on a material to be transferred, a gravure coater method, a relief printing method, a hot melt type coating method, and the like have been used.

[0003] However, according to the gravure coater method, when a solvent-based adhesive is used, the organic solvent has toxicity and explosive properties. Equipment is needed,
When an emulsion-based adhesive is used, a large-scale drying facility for drying is required. In addition, there is a problem that a large amount of equipment is required and that it is not suitable for production of small lots, such as one gravure plate copper is required to form one pattern image.

[0004] In addition, the letterpress printing method has a problem that it is difficult to form a flat coating surface because unevenness in coating thickness is likely to occur.

Further, according to the hot-melt type coating method, usable adhesives are limited to those which can be melted by heat. Therefore, when a precise image is formed, it takes a lot of production time and cleaning is difficult. There are problems such as difficulty in changing agents.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and to form an image of a continuous pattern with a pressure-sensitive adhesive having a uniform coating thickness on a material to be transferred in a short time using simple equipment. It provides a way to:

[0007]

The problem to be solved by the present invention is that the conventional method of forming an image of a continuous pattern with a pressure-sensitive adhesive on a material to be transferred requires a great deal of equipment cost and a small lot production. In addition, it is difficult to form a flat coating surface because the coating thickness tends to be uneven.

[0008]

According to a first aspect of the present invention, a pressure-sensitive adhesive is uniformly applied to a printing surface of a transfer-receiving material on which a pattern has been printed using an ink having a releasing effect. After coating with a release substrate and pressing, the pressure-sensitive adhesive is transferred to the non-printed portion of the printing surface of the transfer target material by releasing the release substrate.

According to a second aspect of the present invention, an adhesive is uniformly applied in advance to a printing surface of one of the two transfer-materials, which has been pattern-printed using an ink having a releasing effect. At the same time, after the printing surface of the other transfer material is overlapped and pressurized, the pressure-sensitive adhesive is transferred to a non-printed portion on the printing surface of the two transfer materials by separating the transfer materials from each other. It is characterized by the following.

[0010]

According to the first aspect of the present invention, when the printing surface of the transfer-receiving material, which has been pattern-printed using an ink having a releasing effect, is coated with a release substrate on which an adhesive is uniformly applied in advance, and the pressure is applied. In addition, the adhesive acts between the adhesive and the release substrate, the printed surface of the transferred material and the adhesive, and the non-printed surface of the transferred material and the adhesive, respectively. Is smaller than the adhesive force between the pressure-sensitive adhesive and the non-printing surface of the release substrate and the transfer-receiving material and the pressure-sensitive adhesive.

Therefore, a continuous pattern of the adhesive can be formed on the non-printed surface of the transfer material when the release substrate is peeled off.

According to the second aspect of the present invention, an adhesive is uniformly applied in advance to one of printing surfaces of two transfer-receiving materials which have been pattern-printed using ink having a releasing effect. When the printing surface of the other transfer material is overlapped and pressurized, adhesive force acts between the printing surface of each transfer material and the adhesive, and the non-print surface of each transfer material and the adhesive. However, the adhesive force between the printing surface of each transfer material and the adhesive is smaller than the adhesive force between the non-print surface of each transfer material and the adhesive.

Therefore, a continuous pattern of the adhesive can be formed on the non-printed surface of each transfer material when the two transfer materials are peeled off.
