ABSTRACT:
The invention discloses crosslinking components for hydroxy and/or primary and/or secondary amine groups containing cationic resins which can be used as binders for stoving paints, particularly for cathodically depositable electrodeposition paints. The crosslinking components are obtained through partial transesterification of transamidation of oligomeric KNOEVENAGEL-reaction products of C-H-active esters and carbonyl compounds with polyols or amines. The products can also be obtained through partial transesterification or transamidation of the C-H-active esters and subsequent KNOEVENAGEL-reaction.
