<P>PROBLEM TO BE SOLVED: To provide an adhesive sheet which has superior adhesive property when the adhesive sheet is attached to a plasticized vinyl chloride resin article, does not decrease adhesion strength even after an autoclave treatment or a storage at low temperature, does not cause lifting or peeling and has excellent blocking resistance. <P>SOLUTION: The adhesive sheet includes a film substrate and a heat-sensitive adhesive layer formed on a backside surface of the film substrate, wherein the heat-sensitive adhesive layer is composed of a resin containing a crystalline polyester resin as a main component. The breaking strength of the film substrate in a flow direction is 10 to 220 N/15 mm; and breaking strength of the film substrate in a cross direction is 10 to 220 N/15 mm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
