FIELD: organic chemistry, cosmetics, dyes. SUBSTANCE: invention relates to composite used for staining keratin materials, in part, human keratin materials, in part, hair. Composite comprises phenylazobenzene compounds including at least one cationic group Z being Z is taken among quaternized aliphatic chains, aliphatic chains containing at least one quaternized saturated cycle and aliphatic chains containing at least one quaternized unsaturated cycle as direct dyes and to methods of direct staining. The use of staining composite provides intense and different colors and exhibits excellent resistance to different treatments that can be used for treatment of keratin fibers. EFFECT: improved methods of staining, valuable properties of dyes. 11 cl, 2 tbl, 3 ex |
