Abstract

Described are aqueous, radiation-curable coating compositions comprising: PA1 a) from 5.0 to 90.0% by weight of at least one water-dispersible polymer P comprising at least one .alpha.,.beta.-ethylenically unsaturated, radiation-polymerizable double bond, PA1 b) from 0.1 to 90% by weight of at least one radiation-curable compound S which is different from P and which is soluble in water or is dilutable with at least 10% by weight of water, based on the overall weight of the coating composition, and which comprises at least one .alpha.,.beta.-ethylenically unsaturated, radiation-polymerizable double bond, PA1 c) from 0 to 20% by weight of a photoinitiator, PA1 d) from 0 to 60% by weight of a filler, PA1 e) from 0 to 20% by weight of further additives, PA1 f) water to 100% by weight and their use.
