Zusammenfassung:	Soluble polymeric colorants composed of free amine groups and chromophoric groups covalently bonded to an organic backbone are disclosed. The number of free amine groups is not less than one-half the number of chromophoric groups. The colorants are characterized by being free of sulfonate, phosphonate and carboxylate groups. The preparation and use of these colorants is also disclosed.
