PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive which excels in the balance of adhesion and readhesion, excels in workability and designing properties, and is particularly suitably used as a pressure-sensitive adhesive for functional films, and a resin composition of the photosensitive type to be used in the pressure-sensitive adhesive. SOLUTION: The resin composition comprises (A) an acrylic copolymer having a weight average molecular weight of 200,000-500,000, (B) a monomer having two unsaturated double bonds in the molecule and an alkylene glycol chain in the molecule, and (C) a photopolymrization initiator, and the pressure-sensitive adhesive excellent in the balance of adhesion and readhesion and in workability and designing properties is prepared by irradiating the above composition with ultraviolet rays.
