Abstract

An adhesive composition comprising monofunctional methacrylate and difunctional methacrylate; wherein the monofunctional methacrylate is a reaction product of a polyether monool and a monoisocyanate having a (meth)acrylic acid group, and the weight average molecular weight of the monofunctional methacrylate is 10,000 to 40,000; wherein the difunctional methacrylate is a reaction product of a polyether polyol, a polyisocyanate compound, and a hydroxyl-containing (meth)acrylate compound, wherein the molecular weight of the polyether polyol, converted from its hydroxyl value, is 3,500 or less, and the weight average molecular weight of the difunctional methacrylate is 10,000 to 50,000; and wherein, relative to 100% by mass of the adhesive composition, the total content of the monofunctional methacrylate and the difunctional methacrylate is greater than 45% by mass.
