Abstract
This invention relates to a radiation curable aqueous coating composition comprising: —from 1 to 99% by weight, relative to the total weight of (1) and (2), of at least one radiation curable aqueously dispersed polyester resin composition (1) comprising an emulsifier D and the reaction product AC of a hydroxy functional polyester resin A and an olefinically unsaturated compound C which can be radically polymerized and which is attached to the polyester resin backbone by an ester linkage or a urethane linkage, and—from 1 to 99% by weight, relative to the total weight of (1) and (2), of at least one other olefinically unsaturated compound (2) selected from the group of: water-dispersible compounds (21); water-soluble compounds (22); and/or water-compatible compounds (23) that have a weight average molecular weight of at least 450 Dalton and are different from the reaction product AC.
