#CMT# #/CMT# Dyeing of keratinous materials comprises applying a tinctorial composition comprising an azomethine dye (I), its optical isomers, geometric isomers, tautomers, solvates such as hydrates, and acid/base addition salts, in a medium. #CMT# : #/CMT# Dyeing of keratinous materials applied comprises applying a tinctorial composition comprising an azomethine dye (I) of formula (R 1>-CR 2>=N-C(CN)=C(CN)-G), its optical isomers, geometric isomers, tautomers, solvates such as hydrates, and acid/base addition salts, in a medium. G : -NR 1>1>R 1>2>or -N=C(R 2>1>)(R 2>2>); R 1>1>, R 1>2>, R 1>, R 2>1>, R 1>1>1>, R 1>2>1>H or alkyl; R 2>, R 2>1>-NR 1>1>1>R 1>2>1>, optionally substituted (hetero)aromatic or arylalkenyl moiety of formula (II), preferably phenyl, naphthyl or 5-6 membered heterocylic or heteroaromatic; X : halo comprising F, Cl, Br or I, alkyl, alkoxy, acylamino or acyloxy; Y 1-NR 1>3>R 1>4>or -N=N-R 1>5>; R 1>5>optionally substituted aromatic; either R 1>3>, R 1>4>H, optionally substituted alkyl, alkoxyalkyl, optionally substituted aryl or 5-6C cycloalkyl or NR 1>3>R 1>4>optionally substituted ring (comprising additional heteroatoms of O or S); n : 0-4; and z : 1-3. Independent claims are included for: (1) a tinctorial composition comprising (I) in a medium with the exception of 2-[(4-bromo-benzylidene)-amino]-3-[(4-diethylamino-benzylidene)-amino]-but-2-enedinitrile and 2-[(4-diethylamino-benzylidene)-amino]-3-[(naphthalen-1-ylmethylene)-amino]-but-2-enedinitrile; and (2) a tinctorial composition comprising (I) in a medium and a polymer thickener and/or a surfactant. #CMT#[Image]#/CMT# #CMT#USE : #/CMT# (I) is useful for dyeing of human keratinous fibers, for dyeing with lightening effect on dark human keratinous fibers having a tone range of = 6, preferably = 4 (claimed). #CMT#ADVANTAGE : #/CMT# (I) provides dyeing of keratinous fibers without any impact on the cosmetic properties of the fiber and without degrading the fiber. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Components: (I) is present in the dyeing composition at 0.001-30 wt.%. (I) is a dye in the range of fluorescent yellow and orange. (I) absorbs the wavelength range of 400-500 nm and reemits the light at a wavelength of 350-680 nm. #CMT#SPECIFIC COMPOUNDS : #/CMT# The use of 54 compounds (I) is specifically claimed e.g. 2,3-bis-[(4-isopropyl-benzylidene)-amino]-but-2-enedinitrile of formula (Ia), 2,3-bis-[(2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-ylmethylene)-amino]-but-2-enedinitrile, 2,3-bis-[(4-methoxy-benzylidene)-amino]-but-2-enedinitrile, 2-({4-[(2-cyano-ethyl)-ethyl-amino]-2-methyl-benzylidene}-amino)-3-{[4-(cyanomethyl-ethyl-amino)-2-methyl-benzylidene]-amino}-but-2-enedinitrile and 2,3-bis-[(2-chloro-4-dimethylamino-benzylidene)-amino]-but-2-enedinitrile. |
