ABSTRACT OF THE DISCLOSURE A fluorine-containing benzophenone derivative of the formula (1), (2) or (3): .PHI.1 (-X1-Q1-Rf1)n (1) .PHI.2-X2-Q2-Rf2-Q3-X3-.PHI.3 (2) .PHI.4-X4-Qf-X5-.PHI.5 (3) wherein .PHI.1 is a 2-hydroxybenzophenone structure of the formula ka-1: Image (ka-1) (wherein Y is a hydrogen atom or a hydroxyl group, each of k and m indicates the number of bond sites, k is an integer of from 0 to 3, and m is an integer of from 0 to 3, provided that 1?(k+m)?4), n corresponds to (k+m) and is an integer of from 1 to 4, each of .PHI.2, .PHI.3, .PHI.4 and .PHI.5 is a 2-hydroxybenzophenone structure of the formula ka-1 wherein (k+m) is 1, each of X1, X2, X3, X4 and X5 is a single bond or an oxygen atom, Q1 is a single bond or a bivalent linking group having a carbon atom directly bonded to X1, each of Q2 and Q3 is a single bond or a bivalent linking group, Rf1 is a monovalent polyfluorohydrocarbon group having from 2 to 22 carbon atoms, in which some of the carbon atoms may be substituted by ether oxygen atoms, Rf2 is a bivalent polyfluorohydrocarbon group having from 2 to 22 carbon atoms, in which some of the carbon atoms may be substituted by ether oxygen atoms, Rf2 is a bivalent polyfluorohydrocarbon group having from 2 to 22 carbon atoms, in which some of the carbon atoms may be substituted by ether oxygen atoms, and Qf is a bivalent linking group having at least one Q4-Rf1 (wherein Q4 is a bivalent linking group, and Rf1 is as defined above).
