    Abstract: The present invention provides a process for preparing aqueous solutions of NCO group blocked resins having polyimide structures and optionally, polyamide structures. The process comprises the steps of preparing a polymer from at least one polyisocyanate, at least one tricarboxylic monoanhydride and/or at least one tetracarboxylic anhydride, and optionally, tricarboxylic acids, tetracarboxylic acids and/or dicarboxylic acids, at least one NH-functional lactam and/or 3,5-dimethylpyrazole and/or butanone oxime. The reaction mixture is subsequently reacted with a base, and the resulting resin is dissolved in water. The resins provide high-grade, highly flexible coatings having the excellent properties and chemical resistance typical of polyamideimides.
