Abstract
Abstract Translated from German Umsetzungsprodukte von mehrfunktionellen Aminen mit Cyanamiden in Gegenwart von Ammoniumsalzen sind leicht in Wasser bzw. wäßrigen Säuren löslich. Reaction products of polyfunctional amines with cyanamides in the presence of ammonium salts are easily soluble in water or aqueous acids. Die Lösungen sind frei von ungelösten Nebenprodukten und eignen sich deshalb hervorragend zur Echtheitsverbesserung von Färbungen mit substantiven Farbstoffen. The solutions are free of undissolved by-products and are therefore ideal for improving the authenticity of dyeings with substantive dyes.
