摘要：
The present invention relates to a radiation-curable aqueous coating composition comprising a polyurethane A comprising as building blocks at least: (a) a polyisocyanate(s) containing at least two cyclic groups, (b) a non-cyclic aliphatic diisocyanate(s) whereby the non-cyclic aliphatic group connecting the two isocyanate groups has from 4 to 36 carbon atoms, and (c) a component(s) containing an isocyanate-reactive group(s), whereby the summed amount of (a) and (b) is 10 to 60 wt.%, relative to the total weight amount of components used to prepare the polyurethane A; and optionally radiation-curable diluent; whereby the weight ratio between (a) and (b) is in the range from 50:50 to 99:1; and whereby the ethylenically unsaturated bond concentration of the coating composition is in the range from 0.5 to 6 milliequivalents per g of polyurethane A and radiation-curable diluent.
