Abstract
New water-soluble polycondensation products are obtained by reaction of polyfunctional amines with cyanamide, its derivatives or polymers in the presence of sulfamic acid. They are excellent fixing agents which improve fastness properties of dyeings with substantive dyestuffs on cellulose fiber materials, paper, board and non-wovens.
