Document Type and Number:
WIPO Patent Application WO/2020/066851
Kind Code:
A1
Abstract:
[Problem] To provide a coating composition that is thermally curable and photocurable, and has improved storage stability so as to form a coated base material having requirements regarding refractive index, hardness, adhesion, transparency, light resistance, flexibility, scratch resistance, adhesion, etc. [Solution] This coating composition comprises: modified metal oxide particles (A) that have an average particle size of 2-100 nm and are obtained by coating the surfaces of colloidal particles (a1) of a metal oxide having an average particle size of 2-60 nm, serving as nuclei, with a layer containing colloidal particles (a2) of a metal oxide having an average primary particle size of 1-40 nm; and a polymerizable compound (B) having an unsaturated bond between a carbon atom and a carbon atom. The metal oxide particles (A) further each have an intermediate layer containing the particles (a2) between the nuclear particle (a1) and the outermost layer containing the particles (a2). The polymerizable compound (B) has a triazinetrione backbone and an unsaturated bond between a carbon atom and a carbon atom. In the present invention, an optical member comprises a base material, and a coating formed on the base material.
