Coatings with improved resistance against suntan lotion.

The present invention relates to an aqueous coating composition CONTAINED BEFORE reaction between components a) and b) A) 10 to 75% by weight, based on the solids content of components a) and c) at least one dispersion or solution of a polyester polyol group containing carboxylate and / or sulphonate, WITH MOLECULAR WEIGHTED AVERAGE weight of 1,000 to 40,000, an OH number of 15 to 100 and an acid number from 2 to 40 BASED ON ALL GROUPS cARBOXYLATE, carboxyl and sulfonate, B) A ester modified polyisocyanate having a functionality NCO average 2 to 6 and contains from 5 to 20 wt% of ester groups (calculated as C 3 O 2 , MW 68) of 5 to 18 wt% GROUP isocyanate and 0 to 20% by weight of hydrophilic groups, non-ionic, chemically incorporated, the percentages based ABOVE IN solids content of the modified polyisocyanate ESTER c) from 25 to 90% by weight, based on the solids content SDE components a) and c) at least one polyurethane dispersion Aqueous, DRYING FISICO group containing carboxylate and / sulfonate, BEING THE COMPONENTS a) and b) present in an equivalent ratio NCO / OH, based on the isocyanate groups COMPONENT B) and hydroxyl groups of component A), of 0.3: 1 to 5: 1. The present invention also relates to coatings prepared from these coating compositions HAVE IMPROVED RESISTANCE TO TANNING LOTIONS.
