2. Description of the Related Art For example, Japanese Utility Model Laid-Open No. 3-36882,
Japanese Utility Model Publication No. 4-2680 or Japanese Utility Model Publication No. 4-243.
Japanese Patent Publication No. 87 proposes a postcard in which the paper surfaces are removably attached to each other.
Postcards can be inexpensively sent as postcards, and because a large space can be obtained, it is not possible to see the contents in direct mail such as department stores or until the pasted part is opened. It is used for payment notices and receipts.

[0003]

However, since the conventional pasting postcards described above are pasted with a special adhesive that can be peeled off after printing the described items, a large amount of direct mail and notification documents are handled. There is a problem that it is practically limited to corporate communication documents and it can not be applied to personal communication, so that such a problem can be solved and a bonded postcard can be created even in a general home. The task was to do so.

[0004]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to the above-mentioned problems in pasting postcards, and after handwriting a communication message or the like, it is possible to attach the removable postcard, and a large amount of information, Another object of the present invention is to provide a bonded postcard sheet which can be easily mailed at low cost by using postcards related to privacy as postcards and which can be easily created at home.

[0005]

In order to achieve the above-mentioned object, the present inventor has conducted diligent studies particularly on the adhesive, and as a result, for example, by applying a household iron, it can be re-peeled so as to be re-adhered many times. Adhesive components that can be matched and that can be handwritten from above after applying an adhesive and that will not cause handwritten characters to bleed due to bonding or to be transferred to the opposite side of the bonding surface I came to find out.

The present invention is based on the above-mentioned findings, and the laminated postcard paper according to claim 1 is such that, when a continuous piece of paper is folded into a postcard, the opposing paper surfaces are removably attached to each other. It is a paper of a laminated postcard to be posted together, and on one of the opposite paper surfaces,
The present invention is characterized in that a heat-sensitive adhesive coating comprising 20 to 45% of a polyolefin copolymer resin, 45 to 70% of a vinyl acetate resin, and 3% or less of an additive is formed. In the case of the bonded postcard paper according to 2, the postcard sheets for three sheets are folded in the lateral direction from the position of the one-third one side in the longitudinal direction, and the opposite paper surfaces are removably pasted together. A postcard for reciprocating laminated postcards, which is heat-sensitive adhesive consisting of 20 to 45% of polyolefin copolymer resin, 45 to 70% of vinyl acetate resin, and 3% or less of additives on one side of the facing paper. The laminated postcard paper according to claim 3 of the present invention is characterized in that the agent film is formed, and the postcard large paper surface for four sheets is a paper piece whose lateral direction is continuous on both sides in the longitudinal direction. A reciprocating laminated postcard sheet that is folded from one-half position and is removably attached to another sheet so that it can be re-separated, and a polyolefin-based copolymer resin 20 to 45 is provided on one of the opposite sheet surfaces. %, Vinyl acetate-based resin 45 to 70%, and an additive 3% or less in a heat-sensitive adhesive film. Is used as a means for solving the problem.

Further, the method for producing a laminated postcard paper according to the present invention comprises a polyolefin-based copolymer resin 10-2.
It is characterized in that a water-based adhesive consisting of 0%, vinyl acetate resin 20 to 30%, additive 1% or less, and water 50 to 60% is applied. Is used as a means for solving the above-mentioned conventional problems.

[0008] In order to use the laminated postcard as a personal communication means, after handwriting a communication message, etc., it can be easily laminated in a general household without peeling off during mailing and after delivery. Must be easily peeled and opened without tearing the paper or scratching the letters, and the adhesive used can be handwritten with letters or illustrations on the surface of the adhesive applied to the paper. At the same time, it is required that the handwritten paper sheets can be easily re-peeled and easily attached to each other, and that the attachment does not cause the characters to be blurred, blurred, or transferred to the opposite side of the paper.

As a result of various studies on the type and components of the adhesive, the present inventor can obtain the above function by setting the adhesive composition within the above range. For example, a household iron is heated and pressed. By doing so, they have found that they can be re-separably attached any number of times.

That is, the polyolefin-based copolymer resin is a component for obtaining the thermal adhesiveness and adhesive strength of the adhesive. If it is less than 20%, it becomes difficult to bond it by heating, and during mailing or the like. The possibility of peeling increases. On the other hand, if it exceeds 45%, re-peeling becomes difficult or the characters after peeling cannot be read.

The vinyl acetate resin is the main component of the adhesive and is a component for obtaining the adhesiveness to the paper surface.
If it is less than 45%, the initial adhesive strength cannot be obtained, and 7
If it exceeds 0%, the adhesive strength becomes too high, and re-peeling becomes difficult.

Additives such as polyvinyl alcohol and calcium carbonate may be added within the range of 3% in order to impart antifoaming property, paintability and adjust viscosity.

The laminated postcard paper according to the present invention is
By applying an adhesive, an adhesive film having the above composition is formed on the specific paper surface. When applying the adhesive, the polyolefin-based copolymer resin 10
An emulsion type water-based adhesive consisting of 20%, vinyl acetate resin 20 to 30%, additives 1% or less, and water 50 to 60% can be applied, and the water based adhesive should be dried on the paper surface. Thus, an adhesive film having the above composition is obtained.

[0014]

In the laminated postcard paper according to the first aspect of the present invention, a continuous piece of paper is folded into a postcard, and one of the opposite paper surfaces has a polyolefin copolymer resin of 20 to 45%. Vinyl acetate resin 45-7
Since a heat-sensitive adhesive film consisting of 0% and 3% or less of additives is formed, after handwriting a message etc., fold it into a postcard and attach it by removably attaching it with a household iron, for example. Become a postcard,
A large amount of documents or documents with confidential contents will be mailed at a relatively low cost as postcards.

The laminated postcard sheets according to claims 2 and 3 of the present invention are for reciprocating postcards, and are one side of a piece of paper in which three or four postcard large paper surfaces are continuous, or With both sides folded, the heat-sensitive adhesive coating of the above composition is formed on one of the opposite paper surfaces, so after handwriting in the same manner as above, fold it into the size of two postcards and re-print it. The releasable pasting makes a reciprocating postcard integrally provided with a reply postcard, and like the pasting postcard according to claim 1, the postcard has a richer content than a normal reciprocating postcard.

In the method for manufacturing a laminated postcard paper according to claim 4 of the present invention, 10 to 20% of a polyolefin copolymer resin, 20 to 30% of a vinyl acetate resin, 1% or less of an additive, and 50 to 60 of water. % Of the emulsion type water-based adhesive is applied, the applied water-based adhesive is dried to form a heat-sensitive adhesive film having the above composition. It is suitable for manufacturing a laminated postcard paper according to No. 3.
