Abstract
There are disclosed quaternary ammonium salts which are obtainable by reacting basic carbamides containing a quaternizable nitrogen atom with epihalohydrins. These quaternary ammonium salts are particularly suitable for enhancing the color yield and the wet fastness properties of dyeings or printings produced on cellulosic fibre materials with anionic dye, e.g. reactive or direct dyes.
