[PROBLEMS] To provide a block copolymer resin composition, a heat-shrinkable multilayer film, and a heat-shrinkable label excellent in adhesion to a polyester-based resin. [MEANS FOR SOLVING PROBLEMS] A resin composition comprising 85 to 99.5 parts by mass of a resin component A and 0.5 to 15 parts by mass of a resin component B, wherein the resin component A contains at least one vinyl aromatic hydrocarbon-conjugated diene block copolymer and the vinyl aromatic hydrocarbon And the conjugated diene is 80/20 to 65/35, the resin component B is a vinyl aromatic hydrocarbon-conjugated copolymer having a mass ratio of vinyl aromatic hydrocarbon and conjugated diene of 30/70 to 0/100 and a number average molecular weight of 5,000 to 40,000 Diene block copolymer or conjugated diene polymer. |
