Abstract
Abstract A curable composition comprising, as the essential components, (A) an organic polymer having a group containing a silicon atom bonded to a hydroxyl group and/or a hydrolyzable group and capable of crosslinking by forming a siloxane bond, (B) a photocurable compound, and (C) a hindered amine series light stabilizer wherein the amino group is a tertiary amino group.
