Curable coating compositions and their preparation and use.

摘要

Film-forming radiation-curable aqueous based coating composition comprising an aqueous latex of a film-forming copolymer preferably having residual unsaturation for cross-linking purposes, preferably a multi-functional cross-linking material and optionally a photoinitiator, wherein the copolymer has a gel fraction of at least l% by weight which has been formed by the early addition of a multi-functional comonomer in the copolymerisation, with a low reactivity multi-functional comonomer preferably being added late in the copolymerisation so as to provide the preferred residual unsaturation.
