    naphthyl;

    pyridinyl, thienyl;

    furanyl;

    or thienyl or furanyl substituted with one to three substituents independently selected from C1-4 alkyl, C1-4 alkyloxy, C1-4 alkylthio, halo, cyano, formyl, acetyl, benzoyl, nitro, C1-4 alkyloxycarbonyl, phenyl, phenylaminocarbonyl and C1-4 alkyloxyiminomethyl;

    or R represents a radical of formula (II) ##STR11## wherein X is oxygen or sulfur;

    Y is nitrogen, CH or C(C1-4 alkyloxy); and

    R" is hydrogen or C1-4 alkyl, and(b) polymers or copolymers derived from monomers selected from the group consisting of dialkyl siloxanes, (meth)acrylic acid, (meth)acrylic acid esters, vinyl and allyl alcohols and derived esters, maleic acid, styrene, vinylchloride, butadiene, acrylamide, acrylonitrile, and resins selected from the group consisting of alkyd resins, polyurethanes, epoxy resins, phenolic resins and ureaformaldehyde resins.
