Abstract

The invention relates to aminourethanes essentially composed of structural units derived from (.alpha.) polyamines of the general formula (I) ##STR1## and of structural units derived from (.beta.) oligomeric or polymeric compounds which contain at least one terminal 2-oxo-1,3-dioxolane group. The invention further relates to a process for preparing these aminourethanes and to their use in particular in paint formulations. The aminourethanes according to the invention are suitable in particular for use as curable water-dispersible binders in particular for cationic electrocoating.
