PROBLEM TO BE SOLVED: To provide a curable coating composition which exhibits excellent weatherability.SOLUTION: The curable coating composition includes: 20-80 pts.mass of (A) component: an isocyanurate ring-containing urethane (meth)acrylate compound shown by general formula (1); 10-70 pts.mass of (B) component: a urethane bond-free isocyanurate ring-containing tri(meth)acrylate compound; 1-35 pts.mass of (C) component; 0.1-10 pts.mass of (D) component: a radical polymerization initiator; 1-12 pts.mass of (E) component: an ultraviolet absorbing agent; and 10-1,000 pts.mass of (F) component: an organic solvent, based on 100 pts.mass of the total of (A) component, (B) component and (C) component. In the formula, R, Rand Reach independently denote a 2-10C divalent organic group; and R, Rand Reach independently denote a hydrogen atom or a methyl group. |
