Abstract

A process for the preparation of polyamides based on diamine radicals and aromatic carboxylic acids characterized in that lower alcohol esters of aromatic dicarboxylic acids are reacted with practically equimolar amounts of diamine in the presence of water with alcohol separation and polycondensation of the product, such as an aqueous solution of the salt, containing the obtained polyamides from 0.3 to 5.9% by weight of lactones C3 to C5 as a light protection agent.
