PURPOSE:To provide the titled paint containing an ultraviolet-curing polyfunctional (meth)acrylate, a urethane-curing polymer and a polyisocyanate compound, etc., at specific ratios, giving a thick coating film by single coating, having excellent brightness, adhesivity, weather resistance, etc., and useful for the coating of vehicles, etc. CONSTITUTION:The objective paint giving a cured film having a gloss retention of >=90% and color difference of <=DELTAE2 after exposure to a sunshine weather-o- meter for 1,000hr can be produced by compounding (A) 20-80wt% (based on the sum of the components A, B and C) polyfunctional (meth)acrylate containing >=2 (meth)acryloyl groups in one molecule and having a number-average molecular weight of 190-2,000, (B) a polyhydride alcohol mono(meth)acrylate polymer having a hydroxyl value of 10-200, (C) a non-yellowing polyisocyanate compound (0.2-1.5 equivalent of isocyanate group of the component C per 1 equivalent of hydroxyl group of the component B), (D) a photo-stabilizer and (E) a photo-polymerization initiator. The sum of the components B and C is 20-80wt% based on A+B+C.
