Abstract:
An active energy beam-curable, pressure-sensitive adhesive sheet, which comprises a substrate and an adhesive layer formed thereon by crosslinking and curing a coat comprising an active energy beam-curable, pressure-sensitive adhesive composition by exposure to an active energy beam, wherein said active energy beam-curable, pressure-sensitive adhesive composition comprises a copolymer of copolymerizable monomers comprising:(a) 0.1-30% by weight of an imide (meth)acrylate represented by the following formula (1), wherein R1 and R2 each independently represents a hydrogen atom or an alkyl group of 4 or less carbon atoms, one of R1 and R2 represents a hydrogen atom whilst the other is an alkyl group of 4 or less carbon atoms, or R1 and R2 are bonded to each other to form a carbon ring; R3 is an alkylene group of 1-6 carbon atoms; R4 represents a hydrogen atom or a methyl group; and n is an integer of 1-6; and(b) 70-99.9% by weight of a monomer containing an ethylenically unsaturated group.
