<P>PROBLEM TO BE SOLVED: To provide a coating composition excellent in non-bleed-out property, compatibility, water resistance, and heat resistance, suppressed in light deterioration, and excellent in durability as compared to the case of using conventional ultraviolet absorbents. <P>SOLUTION: The coating composition is prepared by adding a polyurethane gel particle (C) to a polymer composition comprising an ultraviolet absorbing polymer (A) and a dispersion of a polyurethane (B). The (A) is obtained by polymerizing a compound (a) having a double bond and an ultraviolet absorbing group, and a double bond-containing component (h). The dispersion of (B) is a water dispersion of a product obtained by reacting a compound (b) having an active hydrogen-containing group and an anionic hydrophilic group (excluding a hydroxyl group), a polyol (c) and/or a polyamine (d), and a polyisocyanate (e). The particle diameter of the (C) is 0.5 to 100 μm, and 3 to 200 mass% of (C) is contained based on the total amount of the (A) and (B). <P>COPYRIGHT: (C)2013,JPO&INPIT |
