る。2. Description of the Related Art Conventional pressure-sensitive adhesives for heat-sensitive pressure-sensitive adhesive sheets are used as water-dispersed pressure-sensitive adhesives, as typified by known delayed tack type pressure-sensitive adhesives, in order to maintain the pressure-sensitive adhesiveness after the development of the pressure-sensitive adhesiveness. In many cases. For example, "Adhesion Handbook" (No.
As described in 12th edition, 1980, published by Kobunshi Kogyokai), the composition has a basic skeleton of a thermoplastic resin, a tackifier and a solid plasticizer. Thermoplastic resins are the source of tackiness and adhesiveness. In addition, since solid plasticizers are solid at room temperature, they do not impart plasticity to the resin, and because they melt and swell or soften the resin when heated, they develop tackiness when heated to non-tacky adhesives at room temperature. Acts to cause. At this time, when the tackifier is present, the tackiness becomes more remarkable, and the practical properties are improved.

った。The pressure-sensitive adhesive is applied onto a paper such as high-quality paper, coated paper, art paper, vapor-deposited paper or a plastic substrate sheet such as PET film to produce a heat-sensitive adhesive sheet. The heat-sensitive adhesive sheet is used by heating it at the time of use to develop the adhesiveness and sticking it on a metal, glass or plastic surface as a label or the like. However, when the heat-sensitive adhesive sheet is attached by using a machine (labeler) for attaching to various objects while heating the heat-sensitive adhesive layer of the heat-sensitive adhesive sheet to develop the adhesiveness,
When an accident such as a sticking error occurs, it becomes necessary to easily remove the heat-sensitive adhesive sheet. In this case,
In the heat-sensitive adhesive sheet using the conventional heat-sensitive adhesive,
In particular, when the base material sheet is paper, there is a problem that the base material is broken and wasteful such as washing and discarding again occurs.
