Abstract
A heat-sensitive adhesive material contains a substrate and a heat-sensitive adhesive layer that contains a thermoplastic resin and a solid plasticizer, and the heat-sensitive adhesive material is so configured as to be heated and applied to an adherend, wherein the heat-sensitive adhesive material exhibits such an adhesive strength to the adherend as to increase with time from immediately after applying the heat-sensitive adhesive material to the adherend.
Claims17
A heat-sensitive adhesive material comprising:
- a substrate;
- and
- a heat-sensitive adhesive layer comprising a thermoplastic resin and a solid plasticizer, and being so configured as to be heated and applied to an adherend,
