Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a postcard-attached Japanese paper intended to be attached to a government-made postcard to form a Japanese paper-style postcard.

[0002]

[Prior art]

 Conventionally, a technique of sticking a non-woven thin paper or the like on one surface of a card or a postcard has been known (Jitsukai Sho 62-94068).

[0003]

[Problems to be solved by devising]

 The above-mentioned known technique is one in which another paper is pasted on one side of a postcard made by a government, but it is not heat pasting and reheat peeling is not considered.

For example, once attached, it is difficult to peel off, but there is a problem that peeling off damages the base postcard.

[0005]

[Means for Solving the Problems]

 However, the present invention solves the above-mentioned conventional problems by melting it by low-temperature heating and treating it so that it can be attached or peeled.

That is, this invention is a Japanese paper for sticking to one side of a government-made postcard to form a Japanese paper-style postcard, which can be printed or printed on one side of the Japanese paper and heat-bonded to the other side. It is a Japanese paper for sticking on postcards, characterized by having an adhesive that has both heat resistance and heat release property.

Another invention is a Japanese paper for sticking to one side of a government-made postcard to form a Japanese paper-style postcard, in which an ethylene α-vinyl acetate copolymer resin aqueous dispersion is applied to one side of the Japanese paper. A Japanese paper for postcard sticking, which is characterized in that an aqueous dispersion of an olefin copolymer is added, and a mixed solution of a vinyl acetate resin emulsion containing no plasticizer is further applied and dried.

Low-melting point particles are mixed in the mixture, and the low-melting point particles are melted by heating the other surface of the Japanese paper (the side to which the mixed solution is not applied) with an iron or the like to form a postcard surface. , And firmly adhere to Japanese paper. If the coating amount of the mixed solution is reduced (for example, 5 g / m ^{2 to} 30 g / m ² ), the texture of Japanese paper will be maintained, the majority of ventilation holes will be maintained, and leaching to the surface side (printing surface) There is no fear. Therefore, the appearance is no different from Japanese paper when it is used (printing, writing, etc.).

[0009]

[Action]

 Since the Japanese paper of the present invention is provided with a layer containing heat-melted particles on one surface of a general paper made from paper, heat-bonding or heat-peeling can be facilitated.

[0010]

Example 1 An ethylene-vinyl acetate copolymer resin (Kesipearl V100, manufactured by Mitsui Petrochemical Co., Ltd.) was added to an aqueous dispersion (water content: about 60%) of an ethylene α olefin copolymer (Kesipearl) as a modifier for a thermoplastic resin. A100, manufactured by Mitsui Petrochemical Co., Ltd.), an aqueous dispersion (water content: about 60%) was added, and an emulsion of a vinyl acetate resin containing no plasticizer (water content: 40% to 60%) was added to prepare a water-soluble one-component solution. Make a solution.

The respective ratios can be used within the range of: = 1: 3 to 9: 1: = 9: 1 to 1: 1.

In the above, since the ethylene vinyl acetate copolymer resin is usually difficult to adhere to papers, a mixed solution of isopropyl alcohol (methanol or ethanol) and water-soluble ethylene glycol (for example, 1: 4 to 4: 1) is used. Adhesion is improved by incorporating 1% to 10% into the water-soluble solution.

The Washi product 3 of the present invention can be obtained by applying the solution having improved adhesiveness to one surface of the Washi paper 1 and providing the thin layer 2. In the figure, 4 is a low melting point particle contained in the thin layer 2. In addition, FIG. 2 shows that when the Japanese paper 3 of the present invention is attached to the postcard 5, one side of the postcard 5 and the adhesive side of the Japanese paper 3 are overlapped and heated with an iron to easily bond them.

Further, it can be easily peeled off by reheating and pulling the Japanese paper and the postcard to the opposite side.

[0015]

[Effect of device]

 Since the low melting point particles do not affect the surface side in this invention, there is an effect that the texture of Japanese paper can be maintained and heat bonding or peeling can be easily performed.
