Disclosed are nitro-sulfide dyes of formula (1), their salts, isomers, hydrates and other solvates, wherein R1, R2, R3, independently from each other are hydrogen; C1-C20alkyl or C1-C20alkoxy, which may be substituted by one or more C1-C5alkoxy, halogen,-NH2, mono-C1-C5alkylamino, di-C1-C5alkylamino,-NO2 or hydroxy; C3-C6cycloalkyl;-C(O)H;-C(O)-C1-C5alkyl;-C(O)OH;-C(O)O-C1-C5alkyl; halogen; NO2; OH; SH; phenyl, which may be substituted by one or more C1-C5alkyl, C1-C5alkoxy, halogen,-NH2, mono-C1-C5alkylamino, di-C1-C5alkylamino,-NO2 or hydroxy; or a radical of formula (1a)-NR4R5, wherein R4 and R5 independently from each other are hydrogen; C1-C12alkyl, which may be substituted by one or more C1-C5alkyl, C1-C5-alkoxy, hydroxy or-(CO)-H;-(CO)-C1-C5alkyl; phenyl or phenyl-C1-C4alkyl, wherein the phenyl moiety may be substituted by one or more C1-C5alkyl, C1-C5alkoxy, halogen,-NH2, mono-C1-C5alkylamino, di-C1-C5alkylamino,-NO2, carboxy or hydroxy; or a radical of formula (2); wherein at least one of the radicals R1, R2 or R3 is NO2; Y1 is C1-C10alkylene; C5-C10cycloalkylene; C5-C10arylene; or C5-C10arylene-(C1-C10alkylene) ; Z1 is the direct bond; formula (3) ; or a cationic biradical of a saturated, aromatic or heteroaromatic group; Q1 is-C(O)-;--C(O)O-;-OCO-;-N(R6)-X2-;-CON(R6)-;-(R6)NC(O)-;-O-;-S-;-S(O)-; or-S(O)2-; X1 and X2 independently from each other are the direct bond; C1-C10alkylene; C5-C10cycloalkylene; C5-C10arylene; or C5-C10arylene-(C1-C10alkylene) ; and R6, R7 and R8 independently from each other are hydrogen; C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C1-C10alkyl(C5-C10aryl); m is 1; or 2; U is hydrogen, if m is 1; or the direct bond, if m is 2; with the proviso that the method does not comprise contacting hair with an enzyme of the type of a protein disulfidisomerase (EC 5.3.4.1). Further, the present invention relates to novel sulfide compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation. |
