PROBLEM TO BE SOLVED: To provide a weather resistance, particularly an ultraviolet resistance, comprising an organopolysilsesquioxane having a functional group and a crosslinking agent capable of forming a crosslinked structure by reacting with a functional group of the organopolysilsesquioxane. Provides excellent paint formulations. SOLUTION: An organopolysilsesquioxane (A) in which 50 mol% or more of all side chain functional groups are a hydroxyl group or an epoxy group, and a crosslinking agent (B) capable of reacting with the functional group to form a crosslinked structure; And a coating composition containing an acrylic copolymer (C) having a functional group capable of reacting with the crosslinking agent (B) and, if desired, a pigment. |
