Provided is a coating composition that is capable of forming a coating film having excellent infrared light reflectance and visible light transparency, and also having low haze. The coating composition contains flat pigment particles (1), a resin component, and a curing agent. The flat pigment particles (1) include a laminate (10) of dielectric layers (11) and a metal thin film layer (12). The dielectric layers (11) and the metal thin film layer (12) are layered alternately in the laminate (10) and the dielectric layers (11) are located outermost in the laminate (10). The resin component includes at least one selected from the group consisting of tris(2-acryloyloxyethyl) isocyanurate, 2-hydroxyethylbis(2-acryloyloxyethyl) isocyanurate, 1,3,5-triacryloylhexahydro-1,3,5-triazine, and triglycidyl isocyanurate.
本发明提供了一种涂料组合物,它能够形成具有优异的红外光反射率和可见光透明性的涂膜,而且雾度低。该涂料组合物包含扁平颜料颗粒(1)、树脂成分和固化剂。扁平颜料颗粒(1)包括电介质层(11)和金属薄膜层(12)的层压板(10)。电介质层(11)和金属薄膜层(12)在层压板(10)中交替分层,电介质层(11)位于层压板(10)的最外层。树脂成分包括至少一种选自三(2-丙烯酰氧基乙基)异氰尿酸酯、2-羟乙基双(2-丙烯酰氧基乙基)异氰尿酸酯、1,3,5-三丙烯酰基六氢-1,3,5-三嗪和异氰尿酸三缩水甘油酯组成的组。
