PROBLEM TO BE SOLVED: To provide: a self-adhesive sheet excellent in transparency, wet heat whitening resistance, metallic corrosion resistance, and antifoaming properties; and a photocurable adhesive composition, or the like.SOLUTION: A self-adhesive sheet is obtained by film-forming the following composition through photopolymerization curing. The composition includes: 100 parts of a monomer composition or partial polymerization composition thereof comprising (a) 40-80 parts of a 1-14C alkyl (meth)acrylate monomer or a (meth)acrylate monomer having an alicyclic or aromatic group, and (b) 20-50 parts of a hydroxy group-containing alkyl(meth)acrylate monomer, (meth)acrylamide, N-alkyl substituted (meth)acrylamide, N,N-dialkyl substituted (meth)acrylamide, acryloylmorpholine or N-vinyl-2-pyrrolidone; (c) 0.01-5.0 parts of a crosslinking agent comprising a multifunctional acrylic monomer; (d) 0.1-3.0 parts of a photoradical polymerization initiator; and (e) 0.1-3.0 parts of benzotriazole or derivative thereof. The photocurable adhesive composition comprises this composition. |
