ABSTRACT:
Crosslinking components for cationic paint binders which are reaction products of hydroxyl-functional carbamate compounds with half-blocked diisocyanates are described. The carbamate compounds are reaction products of cyclic organic carbonates with aliphatic monoamines and/or diamines and/or triamines and/or tetraamines and/or alkanolamines, all such amines having primary and/or secondary amino groups. The crosslinking components produced according to the invention, in combination with resin components carrying hydroxyl groups and/or primary or secondary amino groups, preferably with those based on epoxide/amine adducts or containing similar molecular units, give binders which can be baked at temperatures of 140.degree. C. and higher.
