Monoblocked diisocyanates which contain little free and diblocked diisocyanate are obtained by a process which involves adding 1 mole of a blocking agent to a diisocyanate which is present in excess and subsequently removing the excess diisocyanate by thin film evaporation. The compounds produced are useful for the production of cataphoresis resins.
