PROBLEM TO BE SOLVED: To exhibit good weatherability for a long time in a curing composition comprising a polyoxyalkylene-based polymer having reactive silicon groups and a (meth)acrylic ester-based copolymer. SOLUTION: This curing composition comprises 100 pts.wt. of (A) the polyoxyalkylene-based polymer having at least one silicon-containing functional group which is crosslinked by forming a siloxane bond and 20-1000 pts.wt. of (B) the (meth)acrylic ester-based copolymer obtained by copolymerizing a reactive benzotriazole compound as an essential ingredient.
