Patent ID: 8268403

Claim:
A method, comprising: heating a coating composition present on a substrate; and irradiating said coating composition with ultraviolet radiation to cure said coating composition, wherein said coating composition comprises a silicon compound having an —Si—O—Si— structure and an —S 1 —CH 2 —Si— structure, the silicon compound is a hydrolysis-condensation product obtained by hydrolyzing and condensing a hydrolyzable-group-containing silane monomer in the presence of a polycarbosilane, said hydrolyzable-group-containing silane monomer comprises at least one compound selected from the group consisting of a compound represented by formula (2) and a compound represented by formula (3): R 1 a SiX 4-a (2) where each R 1 individually represents a hydrogen atom, a fluorine atom, or a monovalent organic group, each X individually represents a halogen atom, a hydroxyl group, an alkoxy group, or an acyloxy group, and a represents an integer from 0 to 3; R 2 b Y 3-b Si—(R 4 ) d —SiZ 3-c R 3 c (3) where each R 2 and R 3 individually represents a monovalent organic group, b and c individually represent integers from 0 to 2, each R 4 represents an oxygen atom, a phenylene group, or a group —(CH 2 ) e — where e represents an integer from 1 to 6, each Y and Z individually represents a halogen atom, a hydroxyl group, an alkoxy group, or an acyloxy group, and d represents 0 or 1; and said polycarbosilane is a compound represented by formula (1) where each R 8 individually represents a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxy group, an acyloxy group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group, an alkenyl group, or an aryl group, each R 9 individually represents a halogen atom, a hydroxyl group, an alkoxy group, an acyloxy group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group, an alkenyl group, or an aryl group, each R 10 and R 11 individually represents a halogen atom, a hydroxyl group, an alkoxy group, an acyloxy group, a sulfone group, a methanesulfone group, a trifluoromethanesulfone group, an alkyl group having 2 to 6 carbon atoms, an alkenyl group, or an aryl group, each R 12 to R 14 individually represents a methylene group, an alkylene group, an alkenylene group, or an arylene group, provided that at least one of R 12 to R 14 represents a methylene group, and x, y, and z individually represent integers from 0 to 10,000, provided that 5<x+y+z<10,000 is satisfied, and when x=0, one of R 9 , R 10 , and R 11 represents a hydrogen atom, a hydroxyl group, an alkoxy group, an acyloxy group, a sulfone group, a methanesulfone group, or a trifluoromethanesulfone group.
