[PROBLEMS] To realize a coating film having good transparency, optical properties and durability, as well as adhesion and durability to an antireflection film made of an inorganic material, and at the same time, a refractive index of 1 With respect to a base material of .52 or more, interference fringes are eliminated, and the pot life of the coating solution is as long as 3 weeks or more when stored at room temperature. A coating composition comprising at least the following components (A) and (B) as main components. (A). Composite oxide fine particles composed of tin oxide, titanium oxide and zirconium oxide. (B). General formula Wherein R 1 represents an organic group having a polymerizable reactive group, R 2 represents a hydrocarbon group having 1 to 6 carbon atoms, and X 1 represents a hydrolyzable group. Also, n Is 0 or 1. ). |
