Abstract

The present invention relates to an aqueous radiation curable composition comprising: (I) at least one ethylenically unsaturated compound (A), and (II) at least one emulsifier (B) comprising alternating polyalkylene oxide segments, wherein said emulsifier optionally bears one or more groups selected from alkyl groups, aryl groups hydroxyl groups and/or ethylenically unsaturated groups, and wherein said emulsifier (B) has an HLB value of at least 4.5, preferably at least 7. The compositions of the invention are particularly suited for the manufacture of sprayable eco-friendly hardcoats, but they are also suitable for the making of inks, overprint varnishes and adhesives, alone or in combination with e.g. a water-borne polymer dispersion.
