ABSTRACT:
Crosslinking components for cationic paint binders wherein substituted ureas obtained by reacting beta-hydroxyamines with isocyanate compounds are converted into biuret compounds by further reaction with isocyanates. The cross-linking components thus obtained, when combined with base resins containing hydroxyl groups and/or primary or secondary amino groups, yield films having an increased hardening capacity and greater resistance to stone chipping.
