ABSTRACT:
The present invention relates to a process for the production of aqueous dispersions which form powder coatings at room temperature, have an average particle size of 0.1 to 10 .mu.m, contain polyols and blocked polyisocyanate crosslinking agents, and, after stoving, yield coatings with improved water and solvent resistance, in particular on metallic substrates.
