Abstract
Diester-amine adducts of the formula ##EQU1## are provided, wherein A.sub.1 and A.sub.2 each denote alkyklene with 2 or 3 carbon atoms or 2-hydroxy-n-propylene, X.sub.1, X.sub.2 and X.sub.3 each denote hydrogen, alkyl with 1 to 4 carbon atoms or hydroxyalkyl or hydroxyhalogenoalkyl with 2 to 4 carbon atoms or a radical of the formula ##EQU2## and, if n is 3 or 4, the individual X.sub.2 radicals are identical or different, Y.sub.1 denotes hydrogen, alkyl with 1 to 4 carbon atoms or a radical of the formula ##EQU3## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each denote alkyl or alkenyl with 12 to 22 carbon atoms, m, s, s' and s" denote 1 or 2 and n denotes 1, 2, 3 or 4, with the ratio of the diester groups to the nitrogen atoms being at most 1:1. The adducts may be in the form of the free bases, acid salts or quaternary ammonium salts and are useful as agents for imparting a soft handle to organic fibrous materials, especially paper and textiles.
