Abstract
Process for the manufacture of dielectric enamels, characterized in that the pyromellitic acid or some of its derivatives are reacted with a substance selected from the group comprising the aromatic diamines, simultaneously removing from the reaction mixture the water or alcohol optionally formed during the reaction , and adding to the obtained resin a solvent thereof in proportions such that a resinous composition with a solids content between 10 and 30% by weight is obtained.
