New imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives, in particular 5-maleimidyl-trimellitic acid derivatives and 3,5-bis-(maleimidyl)-phthalic acid derivatives, and a process for their manufacture are described. These imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives are suitable for the manufacture of crosslinkable polymers, above all polycondensation and polymerization products, which are distinguished by good processability and good solubility in customary organic solvents. Imidyl compounds, according to the definition, which have anhydride groups can also be used as curing agents for optionally modified epoxide resins.
