Abstract

This invention relates to a process and composition for the production of highly heat-resistant insulating coatings on electrical conductors by coating the conductors with solutions containing catalysts and, levelling agents of thermosetting amide and/or imide-modified ester resins of polyhydric alcohols, polybasic carboxylic acids containing carboxyl groups attached to aromatic rings, optionally in admixture with aliphatic carboxylic acids and, optionally, their anhydrides and/or esters, and compounds containing amino groups, and heating the coated conductors to object temperatures of 150.degree.-400.degree. C.
