PROBLEM TO BE SOLVED: To provide a photocurable elastomer composition which has excellent flexibility and barrier properties when hardened and is small in compression permanent strain.SOLUTION: A photocurable elastomer composition comprises (A) a styrene-based thermoplastic elastomer, (B) a polymer containing at least two reactive functional groups, per molecule, of at least one kind selected from (meth)acrylic, vinyl, vinylidene and maleimide groups, (C) a (meth)acrylate monomer and (D) a photopolymerization initiator, in a mass ratio (A):(B) of 25:75 to 55:45 and a content of (C) of 30-60 mass% with respect to the combined content of (A), (B) and (C). |
