| abstract |
Self-curing cationic amide-group-containing aminourea resins are disclosed, if necessary with urethane groupings, which are the reaction product of at least (A) a polyaminoamide which has been produced from (1) one or more predominantly higher fatty acids and one or more alkylene or polyalkylene-polyamines and/or (2) dimer fatty acids, if necessary in mixture with predominantly higher, substantially unsaturated fatty acids, and one or more alkylene- or polyalkylene-polyamines, and additionally partially contains cyclic amidine-groupings produced under splitting off of water and, if necessary, amino-groups blocked by ketimine, (B) a diisocyanate and, if necessary, of (C) (1) a primary and/or secondary allyl- or methallylamine and/or (2) one or more saturated primary and/or secondary aliphatic, cycloaliphatic, heterocyclic or aromatic amines and/or (3) an allyl- or methallyl-alcohol and/or (4) one or more cyclic or polycyclic alcohols, which are olefinically unsaturated in their cyclic or polyclicic ring systems, and/or (5) a monoalcohol with a tert. N-atom and/or diol with, if necessary, a tertiary N-atom, and have been made dispersible in water with an acid under formation of cationic groups. Also disclosed is a method for the cationic deposition of such resins onto substrates. |
