ABSTRACT:
Production of polycondensates coupled by cyclic imide groups by polycondensing an organic polyisocyanate or a masked organic polyisocyanate, a cyclic carboxylic acid anyhydride which is substituted by at least one further cyclic anhydride group, a carboxyl group, an ester group or an SO.sub.3 H group, and a monohydroxyalkyl ether at a temperature of from 0 to 450.degree. C, lacquers produced therefrom and the use of said lacquers for coating substrates. Typical examples of said monohydroxyalkyl ethers include methyl-, isopropyl, cyclohexyl-, benzyl-, phenyl- and methoxyethyl-ethylene glycol or propylenglycol-monoethers.
