Abstract
Urethane-modified polyoxyalkylene epoxy resins useful in aqueous dispersions having the general formula ##STR1## where R and R.sup.1 are, independently of one another, ##STR2## wherein R.sup.3 is a C.sub.1-3 alkyl group, R.sup.4 is a C.sub.1-4 alkylenemoiety, ##STR3## each b is, independently of one another, an integer from 0 to 4, and c is 1 to 10; a is 1 to 20, and R.sub.2 is H and at least once the group ##STR4## R.sup.6 is a C.sub.1-5 alkyl group, R.sup.7 is H or CH.sub.3 --, d is 1 to 100, e is 0 or 1, f is 0 or 1, and R.sup.8 is an aliphatic, cyclic, alicyclic, aromatic or araliphatic hydrocarbon group.
