The present invention concerns an improved process for printing and dyeing cellulosic textiles, especially cotton, whereby a compounds prepared by first, reacting a dicarboxylic acid with 5 to 22 C-atoms with diethylene triamine in a molar ratio of 1:1 at temperatures of 160 to 220 DEG C, whereby during the reaction the formed water is distilled of, to form a condensation product accordingly, secondly, react the product of step i) at temperatures between 20 and 40 DEG C with epichlorhydrin in a molar ration of 1:1 to form a cationic quaternized product, finally, add sulfuric acid and water to the product of the second step, is used.
