摘要:
An ultraviolet cross-linkable pressure sensitive adhesive sheet includes a (meth)acrylic copolymer of a monomer containing a (meth)acrylic acid ester having an ultraviolet cross-linkable site. The storage modulus of the pressure sensitive adhesive sheet before ultraviolet cross-linking is from 5.0×104 to 1.0×106 Pa at 30° C. and 1 Hz and 5.0×104 Pa or less at 80° C. and 1 Hz. The storage modulus of the pressure sensitive adhesive sheet after ultraviolet cross-linking is 1.0×103 Pa or more at 130° C. and 1 Hz.
