#CMT# #/CMT# Composition for dyeing keratinic fibers comprises a surfactant and/or a thickener and a xanthene dye (I). #CMT# : #/CMT# Composition for dyeing keratinic fibers comprises a surfactant and/or a thickener and a xanthene dye of formula (I) or its mesomeric form (Ia). R 1-R 4H, optionally substituted alkyl, acyl, optionally substituted aryl or optionally substituted N-containing 5- to 12-membered heterocyclyl, or NR 1R 2 and/or NR 3R 4 is optionally substituted N-containing 5- to 12-membered heterocyclyl; R 10halo, alkoxy, alkyl, SO 3H, COOH, NO 2, or amino optionally mono- or disubstituted with benzyl, optionally substituted aryl or optionally substituted alkyl, optionally with both substituents forming optionally substituted N-containing 5- to 12-membered heterocycle or with one substituent forming a 5- or 6-membered heterocycle with an ortho substituent; R-5-R 9H, halo, alkoxy, alkyl, aryl or NO 2, or two of R 5-R 7 can form a fused 5- or 6-membered ring; q : 0-4; An= an anion; p : 0 or 1. Independent claims are also included for: (1) direct dyeing of keratinic fibers by applying a composition comprising a compound (I); (2) dyeing keratinic fibers by applying a composition comprising a compound (I) and optionally developers and couplers and developing the color with an oxidizing agent; (3) device with one compartment containing a dye composition as above and optionally developers and couplers and another compartment containing an oxidizing composition; (4) device with one compartment containing a dye composition as above, another compartment containing a dye composition comprising developers and optionally couplers and another compartment containing an oxidizing composition. #CMT#[Image]#/CMT# #CMT#USE : #/CMT# Compounds (I) are useful for dyeing keratinic fibers, especially human hair (claimed). #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Composition: Thickeners include C12-C30 fatty alcohols. The composition can also contain nitrobenzene, azo, quinone, azine, triarylmethane, indoamine and other xanthene direct dyes. The composition can also contain p-phenylenediamine, bis-phenylalkylenediamine, p-aminophenol, o-aminophenol or heterocyclic developers and m-phenylenediamine, m-aminophenol, m-diphenol, naphthalenic or heterocyclic couplers. #CMT#POLYMERS : #/CMT# Preferred Thickeners: The thickeners include crossllinked polyacrylic acid, crosslinked (meth)acrylic acid/alkyl acrylate copolymers, nonionic (co)polymers of ester- or amide-functional ethylenically unsaturated monomers, ammonium acrylate homopolymers, ammonium acrylate/acrylamide copolymers and polysaccharides. #CMT#SPECIFIC COMPOUNDS : #/CMT# Use of 37 compounds (I) is specifically claimed, e.g. (9-(2-diethylcarbamoylphenyl)-3-xanthenylidene)-diethylammonium chloride. #CMT#EXAMPLE : #/CMT# Composition giving a fuchsia pink color on gray hair comprised (wt.%): (7-(2-diethylcarbamoylphenyl)-benzo[c]xanthen-1-ylidene)-diethylammonium chloride (0.125), alkyl polyglucoside (3), polyethylene glycol 8 (6), benzyl alcohol (4), hydroxyethyl cellulose (0.72), pH 9 buffer (50) and water (to 100). |
