Abstract
At least one monomolecule film is formed on a transparent substrate surface directly or via a protective film. The monomolecule film is formed with chemical coupling of chlorosilane surface active compound, for example, of the formula: EQU F(CF.sub.2).sub.m (CH.sub.2).sub.n SiR.sub.q X.sub.3-q where m is an integer of from 1 to 15, n is an integer of from 0 to 15 provided that the total of m and n is an integer of from 10 to 30 and R is an alkyl or an alkoxyl group, or EQU F(CF.sub.2).sub.m' (CH.sub.2).sub.n' A(CH.sub.2).sub.p SiR.sub.q X.sub.3-q where m' represents an integer ranging from 1 to 8, n' represents an integer ranging from 0 to 2, p represents an integer ranging from 5 to 25, q represents an integer ranging from 0 to 2, X represents a halogen atom or an alkoxyl group, R represents an alkyl or an alkoxyl group, and A represents --O--, a --COO-- or --Si(CH.sub.3).sub.2 --. The transparent substrate such as glass is made hydrophobic and free of contamination.
