Abstract Compounds of aromatic amines with polycarboxylic acids which possess at least 2 glycidyl groups bonded to the nitrogen atoms of the amide groups, such as, for example, N,N''-diglycidylsebacic acid dianilide or N,N''-diglycidyltetrahydrophthalic acid dianilide. These compounds, together with curing agents for epoxide resins, are suitable for the manufacture of mouldings, coatings or adhesive bonds.
