ABSTRACT:
A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte.
The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.
