ABSTRACT OF THE DISCLOSURE Novel phthalic acid derivatives, especially phthalic anhydrides, which are substituted by alkenylamino groups, and a process for their preparation are described. The novel phthalic acid derivatives are valuable intermediates for the preparation of corresponding esters, ester-amides or imides, which, in turn, are used in hot-curable mixtures which are stable on storage and have improved processing characteristics, in particular a prolonged pot life, for the production of mouldings of various types. Phthalic anhydrides substitu- ted by alkenylamino groups, according to the invention, are also suitable as curing agents for epoxide resins. Products or materials cured therewith are distinguished by good mechanical and/or electrical properties.
