Patent ID: 7935424

Claim:
An adhesive sheet comprising: a substrate; and an energy-ray curable adhesive layer formed on said substrate, said energy-ray curable adhesive layer comprising a mixture of an energy-ray curable urethane acrylate; and an energy-ray curable acrylic copolymer, wherein said energy-ray curable acrylic copolymer is a copolymer of at least one of either a dialkyl(meth)acrylamide that has an alkyl group with carbon number of not more than 4, a phenol ethylene oxide (EO) modified (meth)acrylate that has an ethylene glycol chain with a phenyl group bonded to said ethylene glycol chain, or a (meth)acrylate that has an aceto-acetoxyl group, in total of 1 to 30 weight percent of all monomers used to form said energy-ray curable acrylic copolymer, and comprises a side chain comprising an unsaturated group.
