THIOL DYES

Disclosed are thiol dyes of formula (1), wherein R1 is hydrogen; C1-C12alkyl; or phenyl-C1-C4alkyl; X is C1-C12alkylene; C2-C12alkenylene; C5-C10cycloalkylene; C5-C10arylene; or C5-C10arylene-C1-C10alkylene; Y is the residue of an organic dye which corresponds to the formula (1a), wherein R2 is hydrogen; or C1-C5alkyl; R3 is a radical of formula (1a1): (1a2); or (1a3); or R2 and R3 together with the linking carbon atom 1C form a 6 to 10 membered carbocyclic ring which may optionally be a condensated aromatic system and may contain one or more than one hetero atom; and R4, R5 and R6 independently form each other are hydrogen, or C1-C5alkyl; Z is H; or a thio ester group of formula (1b), wherein A is O; S; or N—R9; B is —OR7; —NR7R8, or —SR7; and A is O; S; or N—R9; B is —OR7; —NR7R8, or —SR7; and R7, R8 and R9, independently from each other are hydrogen; C1-C12alkyl C6-C12aryl; or C6-C12aryl-C1-C12alkyl. The compounds are useful for the dyeing of organic materials, such as keratin fibers, preferably human hair.
