Claim:
1. A surface-treating composition comprising a fluorine-containing polymer wherein the surface-treating composition comprises: at least one first compound represented by any of the following general formulae (I) and (II): wherein: Rf is an alkyl group having 1 to 16 carbon atoms which may be substituted by one or more fluorine atoms; R wherein: R wherein: T is a hydroxyl group or a hydrolyzable group; R n is an integer from 1 to 3; R wherein: X is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a halogen atom; and m is an integer of 1-10; and at least one second compound represented by the following general formula (III): wherein: Rf is an alkyl group having 1 to 16 carbon atoms which may be substituted by one or more fluorine atoms; Rf′ is an alkyl group having 1 to 16 carbon atoms which may be substituted by one or more fluorine atoms, a fluorine atom or a hydrogen atom; R wherein: the average molecular weight of the at least one second compound is 2,000 higher or more than the average molecular weight of the at least one first compound.
