Disclosed are triarylmethane dyes of formula (1) D1-(Z1J)r-Y1-S-A, wherein A is hydrogen; a radical of formula (1b) *-S-Y2-(Z2)-D2; or a radical of formula (1c) *-S-Y3; Y1 and Y2 independently from each other are unsubstituted or substituted, straight-chain or branched, interrupted or uninterrupted C1-C10alkylene; C5-C10cycloalkylene; C5-C10arylene; or -C5-C10arylene-(C1-C10alkylene); Y3 is an unsubstituted or substituted, straight-chain or branched, interrupted or uninterrupted C1C10alkyl; C5-C10cycloalkyl; C5-C10aryl; or -C5-C10aryl-(C1-C10alkyl); Z1 and Z2 independently from each other are *-(CH2)p-C(O)-**; *-(CH2CH2-O)-**; *-(CH2)p-C(O)O-**; *-(CH2)p-OCO-**; -(CH2)p-N(R1)-**; -(CH2)p-CON(R1)-**; -(CH2)p-(R1)NC(O)-**; -0-; -S-; -S(O)-; -S(O)2-; or a cationic biradical of a substituted or unsubstituted aromatic or heteroaromatic compound of the formula (1a); (1b); (1c); (1d); or (1e); wherein the asterix * indicates the linkage to D1 and/or D2; the asterix ** indicates the linkage to Y1 and/or Y2; W1 is N or a radical of CR5; R1, R2, R3, R4 and R5 independently from each other are hydrogen; C1-C14alkyl; C2-C14alkenyl; C5-C10aryl; C5-C10aryl-(C1-C10alkyl); or -C1-C10alkyl(C5-C10aryl); D1 and D2 independently from each other are hydrogen; or the residue of an organic dye selected from the radical of formula (1f), wherein B1 and B2, independently from each other are C6-C10aryl; or a 5-7-membered heterocyclic compound, which may be substituted by C1-C12alkyl, C1C12alkoxy, phenyl, hydroxy, halogen, sulfonic acid, carboxylate, or by the radical -NR6R7 or -OR6; B3 is C6-C10arylene, or a bivalent radical of a 5-7-membered heterocyclic compound, which may be substituted by C1-C12alkyl, C1-C12alkoxy, phenyl, hydroxy, halogen, sulfonic acid, carboxylate, or by the radical -NR6R7 or -OR6; R6 and R7 independently from each other are hydrogen; or C1-C12alkyl, which may be substituted by hydroxy or C6-C10aryl; or R6 and R7 together with the linking nitrogen atom form a 5 to 7 membered heterocyclic ring; or R6 and R7 together with the linking nitrogen atom form a piperidine ring of formula (1b)* 1H **. wherein the asterix(*) is directed to Z1 or Z2 respectively; and the asterix(**) is directed to the linking nitrogen atom; wherein one of D1 and D2 is not hydrogen; An is an anion; p is a number from O to 5; r is O or 1; and s is a number from 1 to 5. The compounds are useful for the dyeing of organic materials, such as keratin fibers, preferably human hair.
