Abstract:
1. An adhesive, comprising: a (meth)acrylic acid ester polymer comprising a copolymer comprising ethyl acrylate, butyl acrylate and methoxy ethyl acrylate; a urethane acrylate oligomer having at least four vinyl groups formed by reacting a (meth)acrylate compound containing a hydroxyl group and a plurality of (meth)acrylate groups with an isocyanate trimer; and a silicone graft polymer comprising a (meth)acrylic acid ester monomer at an end of a silicone molecule chain, wherein the (meth)acrylic acid ester monomer is one of a prepolymerization compound, wherein the adhesive comprises at least 20 parts by mass to no more than 200 parts by mass of the urethane acrylate oligomer having at least four vinyl groups and at least 0.1 parts by mass to no more than 10 parts by mass of the silicone graft polymer, with respect to 100 parts by mass of the (meth)acrylic acid ester polymer.
