Abstract

Compounds having a melting point above 40.degree. C. which compounds contain uretone imine groups and which are substantially free from volatile isocyanate blocking agents which are split off under stoving conditions are excellent crosslinking agents for pulverulent coating compositions based on hydroxyl groups-containing polymers.
