Abstract
Radiation curable aqueous compositions (I) with reduced photo-yellowing are provided. Said composition comprises water, at least one ethylenically unsaturated compound and at least one carboxylic acid hydrazide-containing compound (H) in an amount sufficient to reduce photo-yellowing. Materials of the invention have the advantage that they help to reduce photo-yellowing. They may have a beneficial effect on long term yellowing caused by weathering too. Compositions (I) of the invention allow a better quality control of products and materials just after cure. Materials of the invention can be used to make coatings, inks, paints, varnishes and adhesives and they are further suitable for the making of composites, gel coats, 3D-curing and the making of 3D-objects in general.
