Process for the preparation of coatings with hydantoin structures by the reaction of compounds containing carbodiimide groups with unsaturated carboxylic acids

摘要

The invention relates to a process for the production of coatings based on polymers having a hydantoin structure by reacting blocked polyisocyanate carrying carbodiimide and/or uretone imine groups with alpha , beta -unsaturated diicarboxylic acids or derivatives thereof at 50 DEG to 700 DEG C. said reaction being carried out on the substrate to be coated.
