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- groups; 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. |
