摘要

PROBLEM TO BE SOLVED: To provide an active energy ray curable adhesive composition that is transparent after curing, exhibits high adhesiveness to an aromatic film and excellent detergent property and an adhesive for bottle labels using the same.;SOLUTION: The active energy ray curable adhesive composition comprises, in a resin composition comprising at least a copolymer saturated polyester resin, a (meth)acrylate monomer and a photopolymerization initiator, 20-50 pts.wt. of the copolymer saturated polyester resin when the total of the copolymer saturated polyester resin and the (meth)acrylate monomer is 100 pts.wt., and 50-80 pts.wt. of the (meth)acrylate monomer. When the total amount of a polyhydric alcohol component constituting the copolymer saturated polyester resin is 100 mol%, the amount of diethylene glycol is ≥5 and ≤80 mol%, the specific gravity of the copolymer saturated polyester resin at 30°C is ≥1.30 and ≤1.40, the acid value is ≥100 and 500 equivalents/t and the (meth)acrylate monomer has an aromatic ring and a hydroxy group.;COPYRIGHT: (C)2011,JPO&INPIT
