ABSTRACT:
A dye for keratinic material comprises a water-soluble cationic polymer having a molecular weight ranging between about 800 and 10,000 and having secondary, tertiary or quaternary ammonium amine groups wherein said amine groups are either a part of, or aid in the direct or indirect linking to the polymer chain, an aryl or arylaliphatic chromophore or chromogen group carrying compound, with the proviso that when the main chain of the polymer has amine groups derived from the said chromophore or chromogen group carrying compound, the said main chain must also have at least 10 percent aliphatic amine groups relative to the total number of amine groups of the said chain.
