An aqueous coating composition and a process of coating a substrate with such coating composition.

摘要

The invention provides an aqueous coating composition curable at ambient temperature comprising a polyacetoacetate, a polyamino amide having an amine number of 60-1000, and a nitroalkane, a formic acid ester or an organic compound occurring in at least 2 tautomeric forms, and in one of the tautomeric forms a labile hydrogen atoms is linked to a carbon atom. A process of coating a substrate with such composition is also provided.
