SULFIDE DYES

摘要

Disclosed are compounds of formula. Method of dyeing keratin-containing fibers comprising treating the fiber with at least one sulfide dye of formula (1), their salts, isomers, hydrates and other solvates, wherein R₁, R₂, R₃ and R₄ independently from each other are hydrogen; C₁-C₂₀alkyl; C₁-C₂₀alkoxy; C₃-C₆cycloalkyl; halogen; NO₂; OH; SH; or a radical of formula (1a) wherein R₅ is hydrogen; or C₁-C₂₀alkyl; R₆, R₇ and R₈ independently from each other are hydrogen, C₁-C₂₀alkyl, C₄-C₁₂cycloalkyl, C₆-C₁₃aralkyl; phenyl- C₁-C₅alkyl; or R₆ and R₇ together with the linking nitrogen atom form a C₄-C₁₂-membered heterocyclic ring which may be interrupted by one or more than one- O- or -NH- goups; Y₁ is C₁-C₁₀alkylene; C₅-C₁₀cycloalkylene; C₅-C₁₀arylene; or C₅-C₁₀arylene-( C₁-C₁₀alkylene); T₁ is a radical of formula (1b); or -O-(X₃)_s; Q₁ is a cationic biradical of a saturated, aromatic or heteroaromatic group; or a radical of formula (1c); Z₁ is -C(O)-; -(CH₂CH₂-O)_1-5-; -C(O)O-; -OCO-; CON(R₉)-; -X₄-CON(R₉)-; -(R₉)NC(O)-; - O-; -S-; -S(O)-; or -S(O)₂-; R₉, R₁₀ and R₁₁ each independently from each other are hydrogen; C₁-C₁₄alkyl; C₂-C₁₄alkenyl; C₆-C₁₀aryl; C₆-C₁₀aryl- C₁-C₁₀alkyl; or C₁-C₁₀alkyl(C₅-C₁₀aryl); X₁, X₂, X₃ and X₄ independently from each other are C₁-C₁₈alkylene; -(CO)- C₁-C₁₈alkylene, C₁-C₁₈arylene; C₆-C₁₈arylene- C₁-C₁₂alkylene; or -(OCH₂CH₂)_n-O-; n is a number from 1 to 5; p, r, s, t and u independently from each other are a 0 or 1; m is 1; or 2; U is hydrogen, if m is 1; and U is the direct bond, if m is 2. The compounds are useful for the dyeing of organic materials, such as keratin fibers, preferably human hair. The dyes are distinguished by deep dying having good fastness properties with respect to washing, light, shampooing and rubbing.
