Procedure

A polyester is produced in known manner from 388 g of dimethyl terephthalate, 112 g of ethylene glycol and 75 g of glycerin are further worked up as described in Example 1. However, instead of the 137 g of diimidodicarboxylic acid of Example A there is used 125 g of the reaction product of Example G. The obtained lacquer has a solid body content of 33% and a viscosity of 111 seconds and copper wire is lacquered therewith as described in Example 1.
