Abstract:
The present invention relates to an aqueous coating composition comprising polyurethane A and vinyl polymer, wherein the polyurethane A comprising as building blocks at least: (a) a polyisocyanate(s) containing at least one cyclic group, (b) a non-cyclic aliphatic diisocyanate(s) whereby the non-cyclic aliphatic group connecting the two isocyanate groups has 5 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 whereby the weight ratio between (a) and (b) is in the range from 50:50 to 99:1.
