Abstract: The invention concerns the use of indoline derivatives of formula (I): in which R1, R2, R3, R4 and R5 independently of one another represent hydrogen or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they are attached represent a C1-4 alkylenedioxy group, or of salts of such indoline derivatives, as additives to hair dyeing agents of the direct dyeing or primary intermediate/secondary intermediate type, thus producing hair dyeing with excellent color fastness characteristics.

Abstract: The use of indolines of formula (I): in which R1, R2, R3, R4 and R5 independently of one another represent hydrogen or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they are attached may represent an alkylenedioxy group containing 1 to 4 carbon atoms, or their salts, as oxidation dye precursors gives natural brown hair colorings. The indolines of formula (I) are also suitable as couplers in oxidation hair dyes with a conventional primary intermediate, in which they result in a modification of the tints obtainable with the primary intermediate. They are used in conventional carriers, e.g., in gel or emulsion form, preferably mixed before use or on the hair with an oxidizing agent to develop the color.

Abstract: The invention concerns the use of indoline derivatives of formula (I): 1

Abstract: A composition and process for coloring keratin-containing fibers wherein the composition comprises: (a) an alkyl glycoside of the formula (I):R.sup.1 --O--(G).sub.x --H (I)wherein R.sup.1 is a linear or branched alkyl or alkenyl radical having from 12 to 16 carbon atoms, (G) is an anhydroglucose unit, and x is a number from about 1 to about 2.5; (b) an oxidation dye precursor; and (c) a water-based carrier.

Abstract: Aromatic allylaminonitro compounds corresponding to formula (I): ##STR1## in which R.sup.1 is hydrogen or an alkyl group containing 1 to 4 carbon atoms, R.sup.2 is hydrogen, an alkyl group containing 1 to 4 carbon atoms or an allyl group CH.sub.2 C(R.sup.5)=CH.sub.2, where R.sup.5 is hydrogen or an alkyl group containing 1 to 4 carbon atoms, R.sup.3 is carboxyl, hydroxy, nitro, halogen or a group NR.sup.6 R.sup.7, where R.sup.6 and R.sup.7 independently of one another represent hydrogen, an alkyl group containing 1 to 4 carbon atoms, a hydroxyalkyl or dihydroxyalkyl group containing 2 to 4 carbon atoms or an allyl group CH.sub.2 C(R.sup.8)=CH.sub.2, where R.sup.8 is hydrogen or an alkyl group containing 1 to 4 carbon atoms, and R.sup.4 is hydrogen or nitro, with the proviso that R.sup.3 and R.sup.4 are not both nitro. The compounds are useful for dyeing fibers, particularly human hair.
