CURABLE COATING COMPOSITION

摘要

A curable coating composition, which exhibits excellent weather resistance, is provided as a coating for plastic base materials and the like that are used outdoors. This curable coating composition contains: (A) an isocyanurate ring-containing urethane (meth)acrylate compound; (B) a urethane bond-free isocyanurate ring-containing tri(meth)acrylate compound; a component (C) comprising a reaction product of a colloidal silica and an alkoxysilane compound having a maleimide group; (D) a radical polymerization initiator; (E) an ultraviolet absorbing agent; and (F) an organic solvent. (C) jointly uses a component (C-1) obtained by reacting a non-radical-polymerization compound (c1) with a colloidal silica, and a component (C-2) obtained by reacting a radical polymerization compound (c3) with a colloidal silica.
