Abstract:
Disclosed are azo dyes of formula (1) , wherein R1 is hydrogen; C1-C14alkyl; hydroxy- C1-C14alkyl; C2-C14alkenyl; a radical of formula (1a) -(CH2)n1-O-(CH2)n2-CH3; a radical of formula (1b) C10aryl; or C6-C10aryl-C1-C6alkyl; R3 is hydrogen; C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C6alkyl; or CO-R6; R4 is CO-R6; R5 is C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; or C6-C10aryl-C1-C6alkyl; R6 is hydrogen; C1-C14alkyl; C2-C14alkenyl; or C6-C10aryl; R7, R8, R9 and R10, independently from each other are hydrogen; or C1-C5alkyl; m is 1; or 2; An is an anion; If m = 1, R2 is hydrogen; C1-C14alkyl; C2-C14alkenyl; a radical of formula (1a); a radical of formula (1b) ; C6-C10aryl; or C6-C10aryl-C1-C6alkyl; If m = 2, R2 is the direct bond; or C1-C14alkylene, which is optionally substituted by one or more C1-C4alkyl, or which is optionally interrupted by C5-C10arylene, -O- or -NR9R10-; R9 and R10, independently from each other are hydrogen; or C1-C5alkyl; and n1, n2, n3 and n4, independently from each other are a number from 0 to 5. The compounds are useful for the dyeing of organic material, preferably human hair.
