Abstract: The present invention is a copolymer of a monomer mixture including about 25 to about 80 parts by mass of an alkyl (meth)acrylate, approximately 15 to approximately 50 parts by mass of a hydroxyl group-containing monomer, and approximately 5 to approximately 25 parts by mass of a macromer having a glass transition temperature (Tg) of approximately 50° C. or higher. The copolymer contains substantially no acidic groups.

Abstract: A transparent pressure sensitive adhesive sheet with a front surface and a back surface, fabricated by changing the intensity of the ultraviolet light irradiation between the front surface and the back surface. The transparent pressure sensitive adhesive sheet is obtained by ultraviolet light irradiation of an ultraviolet light hardening pressure sensitive adhesive sheet that contains a (meth)acrylic copolymer, a cleavage type photoinitiator, and an ultraviolet light absorber. The amount of ultraviolet light irradiation varies between the first surface and the second surface and the adhesive force varies between the first surface and the second surface.
