ABSTRACT OF DISCLOSURE Crosslinking components for hydroxy and/or primary and/or secondary amino group containing paint binders for the crosslinking of synthetic resins carrying at least two groups capable of ester or amide formation with carboxylic acids. In particular there is disclosed the use of the crosslinking com- ponents in compositions for electrodeposition (ED) whereby at 120°C and above coatings with extraordinary paint performance are obtained. The use of methyl or ethyl esters gives ex- tremely low condensation losses. The crosslinking components are obtained through reaction of one mole of a diisocyanate, preferably at room temperature, in the presence of sodium, or preferably sodium phenolate, as catalyst, with at least one mole of a CH-active alkyl ester of the general formula X-CH2-COOR, wherein X is -COOR, -CN or CH3-CO- and R is an alkyl radical with 1 to 8 C-atoms and subsequent reaction of the free isocyanate groups with polyamines of the general for- mula H2N-(R-NH)n-R-NH2, wherein n is 0 to 3 and/or (poly)- aminoalcohols of the formula N2H-(R-NH)n-R-OH, wherein n is 0 to 3, or HO-(R-NH)n-R-OH, wherein n is 1 to 3, and R is an alkylene radical in all cases.
