摘要

Composition (A) for dyeing keratin-containing fibers, especially human hair, comprises, in a cosmetic carrier, at least one cationic 3-oxo-2,3-dihydro-benzofuran, -benzothiophene or -indole derivative (I) and/or its enol. Composition (A) for dyeing keratin-containing fibers, especially human hair, comprises, in a cosmetic carrier, at least one cationic 3-oxo-2,3-dihydro-benzofuran, -benzothiophene or -indole derivative of formula (I) and/or its enol three of R1-R4 : H, halo, hydro, cyano, nitro, carboxy, sulfonamido, 1-6C alkyl or alkoxy, 2-6C alkenyl, optionally substituted aryl or heterocyclyl, aryl(1-6C)alkyl, 2-6C hydroxyalkoxy or (poly)hydroxyalkyl, or R'R''N-(CH 2) m-, and the last of these four groups is a substituent that carries a quaternary nitrogen; R' and R'' : 1-6C alkyl or alkenyl or aryl(1-6C)alkyl, or together they complete a 5-7 membered ring; m : 0-6; X : O, S or NR5; R5 : H, 1-6C alkyl, 2-6C alkenyl, aryl(1-6C)alkyl, 2-6C (poly)hydroxyalkyl or 1-6C alkoxy(2-6C)alkyl; An : physiologically tolerable anion. An independent claim is included for (I) as new compounds. [Image].
