摘要

PROBLEM TO BE SOLVED: To provide a sol-gel film which has a high strength, has a convex, concave, or irregular surface shape controllable as desired, and can be applied to various functional films.;SOLUTION: The sol-gel film is made of a composition comprising a silica and a dimethyl silicone derivative and has the convex, concave, or irregular surface. The dimethyl silicone derivative has an average degree of polymerization of 5-2,000. A coating liquid for forming the sol-gel film is provided which comprises a solvent, a silica sol, and an alkoxyl-terminated dimethyl silicone derivative having an average degree of polymerization of 5-2,000.;COPYRIGHT: (C)2004,JPO&NCIPI
