Abstract

Abstract Bleed-fast, dyed cellulosics particularly absorbent papers have been obtained with a particular class of water-soluble, cationic dyes reacted with a water-soluble dialdehyde, preferably glyoxal or glutaraldehyde. An aqueous printing fluid containing the water-soluble cationic dye and the dialdehyde, upon drying, produces a water-resistant dyestuff having improved bleed fastness upon cellulosic fibers.
