Disclosed are styryl sulfide dyes of formula (I), wherein R1, R’1, R2, R’2, R3 and R’3 independently from each other are H; C1-C20 alkyl or C1-C20 alkoxy, which may be substituted by one or more C1-C5 alkoxy, halogen, -NH2, mono-C1-C5 alkylamino, di-C1-C5 alkylamino, -NO2 or hydroxy; C3-C6 cycloalkyl; -C(O)H; -C(O)-C1-C5 alkyl; halogen; NO2; OH; Ph, which may be substituted by one or more C1-C5 alkyl, C1-C5 alkoxy, halogen, -NH2, mono-C1-C5 alkylamino, di-C1-C5 alkylamino, -NO2 or hydroxy; or a radical of formula -NR4R5, wherein R4 and R5 independently from each other are H; C1-C12 alkyl, which may be substituted by one or more C1-C5 alkyl, C1-C5 alkoxy, hydroxy or -(CO)-H; -(CO)-C1-C5 alkyl; Ph or phenyl-C1-C4 alkyl, wherein the Ph moiety may be substituted by one or more C1-C5 alkyl, C1-C5 alkoxy, halogen, -NH2, mono-C1-C5 alkylamino, di-C1-C5 alkylamino, -NO2, carboxy or hydroxy; W1, W’1, W2, W’2, W3, W’3, W4 or W’4, independently from each other are -CH- or -N+-; wherein only one of W1/W’1, W2/W’2, W3/W’3, W4/W4′ is -N+; and the bivalent radical -Q-Z-Y-S-S-Y’-Z’-Q’- is bonded to W1 or W2 and W’1 or W’2 resp.; Y1 and Y2 independently from each other are C1-C10 alkylene; C5-C10 cycloalkylene; C5-C12 arylene; or C5-C12 arylene-(C1-C10 alkylene); Q and Q’ independently from each other are the direct bond; or -C(O)-; -C(O)O-; -OCO-; -N(R6)-; -N+(R6)(R7)-; -C(O)N(R6)-; -(R6)NC(O)-; -O-; -S-; -S(O)-; or -S(O)2-; and R6 and R7 independently from each other are H. Further, the present invention relates to novel styryl sulfide compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation The novel styryl sulfide dyes are useful for the dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or polyamides, especially keratin-containing fibers, cotton or nylon, and human hair. The experimental process involved the reaction of 2-(Methylamino)ethan-1-ol hydrochloride(cas: 62640-03-3).Computed Properties of 62640-03-3
