。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 can be maintained for a long time after heat activation.

There was a problem in that it required a process of leaving it for a very long time.

Therefore, a second object of the present invention is to produce a heat-activated pressure-sensitive adhesive sheet that can maintain adhesiveness and adhesion for a sufficiently long time even on plastic materials with low polarity.

）が短くなることから実用的ではない。(D) Means for Solving the Problems In view of the above, the present inventor first proposed that each material of the composition be used in the form of a coating composition in order to coat the 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 that do not cause the pressure-sensitive adhesive sheet to be 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, it was not possible to obtain sufficiently long adhesiveness and adhesion to plastic materials with low polarity using conventionally known aqueous dispersions of polymeric materials such as those mentioned above in heat-activated adhesive sheets. ,
As a result of extensive research on other polymers, it was finally discovered that by using a polyurethane emulsion as part or all of the polymer material, a heat-activated adhesive sheet that can maintain sufficient adhesiveness and adhesion for a long period of time can be obtained. was able to achieve this. Such a heat-activated pressure-sensitive adhesive sheet produced by water-based coating using a polyurethane emulsion is not yet known. A preferred blending ratio of the polymer material, tackifier and solid plasticizer is 10 parts of the polymer material.
The amount of tackifier is 10 to 120 to 0ffiffi part.
In the car body, 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 up into a roll. If the solid plasticizer is less than 50 parts by weight, tackiness due to thermal activation is unlikely to occur;
If it exceeds 300 weight parts, the cohesive force of the adhesive part after heat activation will decrease and the duration of adhesion (open time) after heat activation will become short, which is not practical.

対処できる。Polyurethane emulsions can be classified into polyether-based, polyester-based, aromatic isocyanate-based, aliphatic isocyanate-based, etc. based on their raw materials, but any of them can be used, and the application of the adhesive sheet and heat activation conditions This can be handled by selecting the raw material of the resin, the molecular weight of the polymer, etc., depending on (heating temperature, heating time), application conditions (application pressure, time until application, VI quality/form of the adherend), etc.
