Abstract

The present invention relates to a radiation curable aqueous composition comprising at least one ethylenically unsaturated polymer (1) which is the reaction product of—a water-dispersible (meth)acrylic polymer A containing pendant hydroxyl or isocyanate groups, and containing pendant groups capable to render the polymer dispersible in aqueous medium either directly or after reaction with a neutralizing agent; —at least one ethylenically unsaturated compound B which can be radically polymerized under irradiation and which attaches to the (meth)acrylic polymer A by an urethane linkage; —and, optionally, at least one neutralizing agent C. The present invention further relates to the making and use of such radiation curable aqueous compositions.
