Abstract
Polymeric compounds (A) obtained by the reaction of epihalo-hydrin with a polyalkylene polyamine are useful as textile treatment agents. As pretreatment agents they improve the color yield of the subsequent dyeing, as aftertreatment agents they improve fastness properties. Certain of the products (A) are novel.
