る。 Here, the polymeric material is the source of adhesive strength, and the tackifier is a component that increases tackiness when activated by heating. A solid plasticizer is solid at room temperature and does not impart plasticity to the polymeric material, but when heated, it melts and causes the polymeric material to swell and dissolve to develop tackiness. Once melted, it crystallizes slowly, so that the adhesive retention time of the adhesive sheet after heat activation can be extended.

シートを製造することである。 In addition, conventional heat-activated pressure-sensitive adhesive sheets tend to peel off from the adherend at an early stage after application, especially when applied to plastic materials with low polarity, resulting in poor practical value. Therefore, the second aspect of the present invention
The purpose of the present invention is to produce a heat-activated adhesive sheet that can maintain adhesive properties for a sufficiently long time even on plastic materials with low polarity.

ることから実用的ではない。(D) Means for Solving the Problems Based on the above, the present inventor first developed a coating composition in which each material of the composition is coated with a solid plasticizer in a solid state. We chose to formulate it into an aqueous dispersion and create an aqueous coating solution. As a result, it was possible to directly produce a heat-activated pressure-sensitive adhesive sheet that does not cause blocking even when wound into a roll by selecting drying conditions such that the pressure-sensitive adhesive sheet is not thermally activated. It has also been found that blocking can be further prevented by increasing the pulverized particle size of the solid plasticizer to an extent that does not impede the smoothness of the coated surface. This was a major advantage of preparing each material in the form of an aqueous dispersion and applying it. On the other hand, with regard to adhesion, when using a conventionally known aqueous dispersion of a polymeric material such as the one mentioned above in a heat-activated adhesive sheet, it is not possible to obtain sufficient long-term tack/adhesion to plastic materials with low polarity. As a result of extensive research on other polymers, it was finally discovered that by using polyurethane emulsion as part or all of the polymer material, a heat-activated adhesive sheet that can maintain sufficient adhesiveness and adhesive properties for a long period of time can be obtained. The above objective was achieved. Such a heat-activated pressure-sensitive adhesive sheet produced by water-based coating using a polyurethane emulsion has not yet been known. The preferred blending ratio of the polymer material, tackifier, and solid plasticizer is as follows:
For 100 parts by weight, the tackifier is 10 to 120 parts by weight, the solid plasticizer is 50 to 300 parts by weight, and the polyurethane emulsion is 20 to 100 parts by weight of the polymer material.
% by weight can achieve the objectives of the present invention.
If the tackifier is less than 10 parts by weight, the tackiness and adhesive strength after heat activation will be low, and if it exceeds 120 parts by weight, the blocking phenomenon will become severe when wound into a roll.
If the solid plasticizer is less than 50 parts by weight, the development of adhesiveness due to heat activation will be difficult to occur, and if it exceeds 300 parts by weight, the cohesive force of the adhesive part after heat activation will decrease, and the adhesive duration after heat activation (open It is not practical because the time (time) becomes short.

This can be handled by selecting the raw material of the resin, the molecular weight of the polymer, etc. depending on the conditions (heating temperature, heating time), application conditions (application pressure, time until application, material/form of the adherend), etc.
