Patent ID: 8791196

Claim:
An adhesive composition for labels comprising: a block copolymer A represented by the following general formula (A); a polymer C, which is a polymer having a glass transition temperature of −30° C. or lower, or a block copolymer that has a polymer block having a glass transition temperature of −30° C. or lower at an end of a polymer chain; and a tackifier resin D; Ar1 a -D a -Ar2 a (A), in the general formula (A), Ar1 a represents an aromatic vinyl polymer block having a weight average molecular weight of 6,000 to 20,000; Ar2 a represents an aromatic vinyl polymer block having a weight average molecular weight of 22,000 to 400,000; a ratio (Mw(Ar2 a )/Mw(Ar1 a )) of the weight average molecular weight (Mw(Ar2 a )) of the aromatic vinyl polymer block (Ar2 a ) and the weight average molecular weight (Mw(Ar1 a )) of the aromatic vinyl polymer block (Ar1 a ) is 1.5 to 67; and D a represents a conjugated diene polymer block having a vinyl bond content of 1 mol % to 20 mol %.
