| abstract |
A coating liquid for forming a transparent film, comprising an inorganic oxide precursor, and an organosilicon compound or a product obtained by hydrolysis and condensation polymerization of the organosilicon compound, said organosilicon compound represented by the formula: wherein each of R1 and R2 represents an alkyl group, a halogenated alkyl group, an aryl group, etc.; each of R3 to R6 represents an alkoxy group, an alkyl group, a halogenated alkyl group, an aryl group, etc.; and X represents -(CH2)n-, -(Ph)-, -(CH2)n-(Ph)-, -(CH2)n-(Ph)-(CH2)n-, -(S)m- or -(CH2)n-(S)m-(CH2)n-, provided that Ph represents a benzene ring, m is an integer of 1 to 30 and n is an integer of 1 to 30. A transparent film which exhibits excellent performance in, for example, oxidation inhibition, rust prevention, chemical resistance, scuffing resistance, weather resistance and antireflection can be formed from the coating liquid. |
