Coating compositions obtained by reacting amino carboxylic acids derivatives with polyisocyanates and compounds containing carboxylic groups to produce polymers containing hydantoin rings and amide groups

摘要

In non-phenolic solvents soluble Polyamid-hydantoins optionally containing ester and/or imide and/or isocyanurate groups are obtained by reacting polyisocyanates with polyfunctional amino carboxylic acid derivatives and a compound containing at least a carboxylic group preferably in the presence of a non-phenolic solvent.
