Patent ID: 11634589

Abstract:
There are provided a coating composition being possible to form a cured film which has excellent transparency and weather resistance, and especially hardness. A coating composition obtained by which a silicon-containing substance as a component (M) and a silica colloidal particle having a primary particle diameter of 2 to 80 nm as a component (S) are mixed, and then the component (M) is hydrolyzed, and the resulting aqueous solution is subsequently mixed with a colloidal particle (C) wherein a component (F) is a modified metal oxide colloidal particle (C) having a primary particle diameter of 2 to 100 nm, which includes a metal oxide colloidal particle (A) having a primary particle diameter of 2 to 60 nm as a core, whose surface is coated with a coating (B) formed of an acidic oxide colloidal particle.
