Abstract of the Disclosure This invention is concerned with coating composi- tions comprising an unsaturated polyol/polycarboxylic acid alkyd or polyester condensate resin (including drying oil- modified alkyd), the polycarboxylic acid or anhydride percursor(s) of which alkyd may be aromatic, aliphatlc, or both. In one preferred embodiment Type A, the polyacid is prredominantly or exclusively aliphatic and in another Type B, it is predominantly or exclusively aromatic in character. The alkyd or polyester is carried (dissolved) predominantly or exclusively in a substantially non-volatile reactive liquid consisting essentially of a) dicyclopentenyl acrylate or methacrylate or mixtures thereof or of b) a mixture of such (meth)acrylate with one or more alkyl or alkenyl esters of acrylic or methacrylic acid in which the alkyl and/or alkenyl group contains 10 to 20 carbon atoms. The composi- tion also contain a polyvalent metal-containing drier or ??ccative optionally a volatile agent for inhibiting the action of the drier, i.e., a fugitive stabilizer; they may also contain pigments, rheology control agents, pigment- dispersing agents, and other components.
