摘要

The present invention relates to aluminum pigments and (iii) at least 200 milligrams of chemically added carbonate groups -O-CO-O- per 100 g of solids and (ii) a total amount of chemically added urethane groups of up to 320 milliliters per 100 g of solids. It relates to an aqueous coating composition containing a water dispersible polyurethane polyurea binder containing -NH-CO-O- and a chemically added urea group -NH-CO-NH.;The present invention further relates to coatings made from aqueous coating compositions.
