Abstract
A curable composition is described, comprising a) 10 to 90% by weight of at least one, optionally water-dilutable, water-emulsifiable or water-dispersible, epoxy resin having more than one epoxy group in the molecule; b) 90 to 10% by weight of at least one polyamine adduct which predominantly corresponds to the idealised formula (I) and which is prepared from an adduct of formula (A) and a polyamine of formula (XII), wherein the sum of the percentages by weight of components (a) and (b) is always 100%; c) optionally, at least one further aliphatic, cycloaliphatic, aromatic/aliphatic, aromatic or heteroaromatic mono- or polyamine which may optionally be modified by adduction; and d) optionally, at least one customary additive, R.sup.1 and R.sup.2 and also m and n and B being defined in more detail in the description. The novel compositions are used for the preparation of colourants and coatings. ##STR1##
