Abstract:
Provided is a coating composition which is suitable for use in in-mold coating and particularly suitable for use in a coating material for exterior use. This two-component type coating composition contains a main agent and a curing agent. The main agent contains a polyol, a curing catalyst and a photostabilizer. The curing agent contains an isocyanurate compound. The hydroxyl value of the polyol is 300-1000 mg KOH/g. The average number of hydroxyl groups in the polyol is 3 or more. The content of the curing catalyst is 0.25-10 parts by mass relative to 100 parts by mass of the polyol. The photostabilizer contains a hindered amine compound. The common logarithm pKb of the base dissociation constant of the hindered amine compound is 6.5-14. The content of a solvent is 30 mass% or less.
