<P>PROBLEM TO BE SOLVED: To provide an adhesive sheet which is tough, has extensibility, and is excellent in weather resistance and chemical resistance, and in which even if it is adhered to the ground of a flexible polyvinyl chloride or the like containing a low molecular weight plasticizer of high transition nature much, the abnormalities in the appearance such as wrinkle and swelling are not generated. <P>SOLUTION: The adhesive sheet includes a substrate, and an adhesive layer, wherein the substrate is formed by a resin composition (E) which includes: a vinyl polymer (A) which has one or more sorts of structures in a side chain having a functional group which can react with an isocyanate group, and is chosen from the group consisting of polyether, polyester, polycarbonate, and polybutadiene; at least one sort (B) which has two or more functional groups which can react with an isocyanate group, and is chosen from a polyether, polyester, polycarbonate, and polybutadiene; an isocyanate compound (C) which has two or more isocyanate groups; and an epoxy compound (D) which has two or more epoxy groups. <P>COPYRIGHT: (C)2012,JPO&INPIT |
