<P>PROBLEM TO BE SOLVED: To provide an adhesive usable for decorative adhesive sheets, excellent in outdoor weather resistance, having good adhesion to olefin-based materials, causing neither floating nor peeling when adhered on an uneven surface and, after use, capable of peeled without remaining paste. <P>SOLUTION: There is provided an adhesive for decorative sheets which adhesive comprises an acrylic polymer (A) having a glass transition temperature of -70 to -10°C and a weight-average molecular weight of 800,000 to 2,000,000 and provided by solution polymerization, an acrylic polymer (B) having a glass transition temperature of ≥-10°C and <40°C and a weight-average molecular weight of 1 and ≤100,000 and provided by solution polymerization, and a crosslinking agent (C), wherein the acrylic polymer (B) is a copolymer obtained by reacting a methacrylic alkyl ester having at least a 2-6C alkyl chain, and the adhesive for decorative sheets uses the acrylic polymer (A) and the acrylic polymer (B) at a weight ratio of from 50/50 to 95/5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
