A moisture-curing binder composition useful in paints and other coating compositions is prepared by mixing or mixing with spontaneous reaction in the absence of moisture A) 30 to 99 parts by weight of at least one compound containing at least two intramolecular carboxylic anhydride groups and B) 1 to 70 parts by weight of organic compounds having blocked amino groups, wherein B) comprises organic compounds containing hydrogen atoms which are reactive to acid anhydride groups and containing bicyclic amide acetal or bicyclic amide aminal groups or both, wherein the ratios of the amounts of the individual components are chosen such that, by taking into account the addition reaction which occurs spontaneously between components A) and B) in the absence of moisture, in the resulting mixture 0.25 to 50 anhydride groups are present per bicyclic amide acetal and bicyclic amide aminal group.
