Abstract
A resin composition for insulating coating material, comprises: a polyimide resin and/or a precursor thereof; and a polymer having a heterocyclic ring at a side chain, wherein the content of the polymer having a heterocyclic ring at a side chain is 0.1 to 7 parts by weight relative to 100 parts by weight of the polyimide resin and/or the precursor thereof. By adding a prescribed amount of the polymer having a heterocyclic ring at a side chain, there can be obtained a resin composition for insulating coating material still maintaining heat resistance and together having excellent bending resistance.
