Abstract

New polyamide-ester resins, their manufacture and the new compositions manufactured therefrom, the latter being useful for enameling metal conductors. The enameled conductors are stable at relatively high temperatures. The resins are manufactured from a polycarboxylic component, a part of which is a 2,4-quinazoline dione dicarboxylic compound, a polyamine component and a polyhydroxy component.
