  • Adhesive sheet
    Patent number: 8178198
    Abstract: An adhesive sheet includes a substrate and an energy-ray curable adhesive layer formed on the substrate. The energy-ray curable adhesive layer includes an energy-ray curable acrylic copolymer and a urethane acrylate. The energy-ray curable acrylic copolymer is formed by copolymerizing at least one of either a dialkyl(meth)acrylamide that has an alkyl group with carbon number of not more than 4, a phenol EO modified (meth)acrylate that has an ethylene glycol chain with a phenyl group bonded to the ethylene glycol chain, a (meth)acryloyl morpholine, or a (meth)acrylate that has an aceto-acetoxyl group, in total of 1 to 30 weight percent of all monomers to form the energy-ray curable acrylic copolymer. The energy-ray curable acrylic copolymer further includes a side chain with an unsaturated group.
    Type: Grant
