摘要: Aqueous-based, film-forming and ambient-temperature autoxidisably crosslinkable coating composition comprising an aqueous latex of a film-forming copolymer having residual unsaturation for autoxidative cross-linking puuposes, an autoxidation catalyst, preferably a drier salt, and optionally a multi-functional crosslinking material, wherein the copolymer has a gel fraction of at least 5% by weight which has been formed by the early addition of a multi-functional comonomer in the copolymerization, with a low reactivity multi-functional comonomer being added late in the copolymerization to provide the residual unsaturation.
