摘要:
Oxidation colorants for coloring keratinous fibers comprising a primary intermediate and a secondary intermediate, wherein the primary intermediate comprises: a) a pyrimidine derivative wherein the pyrimidine ring is substituted with two to four amino groups and zero to two hydroxy groups; and b) 1-(2′-hydroxyethyl)-2,5-diaminobenzene or 2-(2′-hydroxyethylamino) -5-aminotoluene.
摘要:
A hybrid dye is provided that is useful for coloring keratin fibers and skin. The hybrid dye has the structure X-S-Y, where X is derived from a substantive dye, Y is derived from an oxidation dye precursor or a melanin precursor, and S is a direct bond or spacer group. The present invention also provides a composition for coloring keratin fibers that contains the hybrid dye.
摘要:
A composition and method for using the composition for dyeing keratin fibers. The composition consists of indole/indoline hybrid dyes and hybrid dye precursors. More particularly, the indole/indoline hybrid dyes and hybrid dye precursors correspond to formula (I): X—S—Y (I) where X is a group derived from an indole or indoline derivative as a melanin precursor, Y is a group derived from an oxidation dye precursor of the secondary or primary intermediate type or an indole or indoline derivative as a melanin precursor; and S is a structural element which is common constituent of the groups X and Y, a direct bond or at least one spacer group. The composition may also be used to color human skin.
摘要:
Oxidation dyes that contain a developer-coupler combination of 2-(2,5-diaminophenyl)-ethanol or its salt with an organic or inorganic acid and 2-chloro-6-methyl-3-aminophenol or its salt with an organic or inorganic acid are characterized by intensive blue finishes with high rubbing fastness.

A 1,4-diazacycloheptane derivative and an oxidative hair colorant containing the derivative as a primary intermediate is presented. The 1,4-diazacycloheptane derivative is of the formula: ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another represent hydrogen, a C.sub.1-4 alkyl or hydroxyalkyl group or a C.sub.2-4, dihydroxyalkyl group, X and Y independently of one another represent hydrogen, chlorine, fluorine, a C.sub.1-4 alkyl, hydroxyalkyl, aminoakyl or alkoxy group, a C.sub.2-4 dihydroxyalkyl group or an allyl group and R.sup.5 and R.sup.6 independently of one another represent hydrogen or a C.sub.1-4 alkyl group. Natural color tones can be obtained in keratin fibers with oxidative hair colorants containing the 1,4-diazacycloheptane derivative, without the use of additional primary intermediates.
摘要:
1,3-disubstitued nitrobenzenes of the general formula I: ##STR1## in which X is a hydroxyl group or an amino group and R.sup.1 is hydrogen or a C.sub.1-4 alkyl group and their salts are suitable for use as an oxidation dye precursor of the coupler type, together with prior art primary intermediate components, for the production of oxidation dyes, preferably for the production of hair colorants. With developers of the p-phenylenediamine, p-aminophenol, 2.5-diaminopyridine, and 2,4,5,6-tetraaminopyrimidine types, primarily brown hues with great light stability are formed.
