Title:
COATING COMPOSITION
Document Type and Number:
Japanese Patent JP2013067793
Kind Code:
A
Abstract:

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.

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).
