る。(Prior Art) Stamps such as ordinary stamps and revenue stamps are used in which a water-soluble polymer adhesive such as dextrin, starch or polyvinyl alcohol is applied to the back surface.
Therefore, when a stamp collector removes used stamps from postcards, envelopes, etc., they can easily remove them by soaking them in water. However, when affixing stamps to postcards, envelopes, etc., a method is used in which the water-soluble adhesive layer surface is wetted with water, for example. However, there are times when there is no water at hand when sticking stamps. In such cases, they are often wetted with saliva and applied. This is not very hygienic, nor is it visually pleasing. Therefore, a stamp paper sheet in a form that can be applied as it is without being wet with water or saliva is introduced in Japanese Utility Model Publication No. 56-108167. That is, the stamp paper sheet described in this document is made by sticking a government-made stamp on the back side of which a water-soluble adhesive is applied via a viscous adhesive, and peeling the stamp from the release paper. If so, it can be pasted as it is. However, in the case of actually constructing this kind of stamp paper sheet, since the adhesive force between the stamp paper (water-soluble adhesive layer) and the adhesive layer is not sufficient, the stamp paper after pasting must not be soaked in water. However, it has been found that there is a problem that it is easily peeled off between the water-soluble adhesive layer and the pressure-sensitive adhesive layer. If the applied stamp is easily peeled off, the suitability as a stamp is lacking from a practical point of view. Therefore, it is necessary to solve this problem in order to make it practically usable.

ものにすることが考えられる。In addition, conventional labels, stickers, patches, delivery slips, etc. made of an adhesive sheet are characterized in that they can be attached to an adherend as they are without being wet with water. Once pasted, even if one tries to peel it from a used one for collecting or other purposes, it cannot be easily peeled from the pasted one. Therefore, if you wish to peel off such labels, seals and patches from used adherends for other purposes, you can easily soak them in water as in the case of the stamps mentioned above. It is conceivable that the back surface is provided with a water-soluble adhesive layer so that it can be peeled off.

If the amount is 3% by weight or less, the adhesive strength between the water-soluble adhesive layer and the pressure-sensitive adhesive layer cannot be sufficiently exhibited. On the other hand, if the content of 95% by weight or more is contained, the releasability is poor even when immersed in water in order to peel it from the adherend, and the intended product cannot be obtained.

The dry coating amount is preferably about 2 to 20 g / m 2 . 2g
If it is less than / m 2 , sufficient releasability cannot be obtained even when immersed in water.
Further, if it is 20 g / m 2 or more, the necessity is poor in terms of the effect.

きる。On the other hand, it is not clear why the inclusion of a pigment in the water-soluble adhesive layer applied to the back surface dramatically improves the bonding force between the adhesive layer and the adhesive layer. It is thought that this is because the anchoring effect is exerted as well as the electrical coupling effect due to the metal ions of the pigment is added. When a water-soluble adhesive is applied and wound up, blocking is likely to occur, and this tendency is particularly strong when dextrin is used. However, when a pigment is contained therein, the occurrence of blocking can be effectively improved.

In the above, since the bonding strength between the water-soluble adhesive layer and the pressure-sensitive adhesive layer has been insufficient so far, the water-soluble adhesive layer is easily peeled off during this period, which is not suitable for practical use. By including a pigment in the composition, it is possible to increase the bonding strength and to provide a product having sufficient practical suitability.
