Abstract

Heat-curable surface-coating agents useful in organically dissolved baking finishes, for powder coating and for cathodic electrocoating contain, as a binder, a mixture of a polyadduct, polycondensate or other polymer which has an average molecular weight M.sub.n of from 500 to 10,000 and, per molecule, on average two or more OH and/or NH groups, and a reaction product of a polyamine which contains on average two or more primary amino groups per molecule and a cyclic carbonic acid ester of the formula (I) ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each are hydrogen, methyl or ethyl.
