摘要:
The 3-aminophenol derivatives of formula (I), or the physiologically compatible, water-soluble salts thereof: wherein R1 represents a group of formula (II) or a group of formula (III): are useful as couplers in hair colorants. Agents for dyeing keratin fibers, especially hair, based on a developer-coupler combination containing these compounds and methods of dyeing using these agents are described.
摘要:
The object of the invention are (p-aminohydroxyphenyl)acrylamide derivatives of general formula (I) or the physiologically tolerated, water-soluble salts thereof and oxidative coloring agents for keratin fibers, containing these compounds.
摘要:
Dyeing agents for keratin fibers, containing N-heteroarylmethyl-m-phenylenediamine derivatives of general formula (I) or the salts thereof and new N-heteroarylmethyl-m-phenylenediamine derivatives.
摘要:
1,4-Diamino-2-alkenylbenzene derivatives of general formula (I) or physiologically tolerated water-soluble salts thereof as well as agents for oxidative dyeing of fibers, containing these compounds.
摘要:
The present patent application relates to 3-(2,5-diaminophenyl)acrylamide derivatives of general formula (I) or to physiologically tolerated, water-soluble-salts thereof and to agents containing said compounds and used for oxidative dyeing of fibers.
摘要:
New p-diaminobenzene derivative compounds of the formula (I): ##STR1## and physiologically compatible water soluble salts thereof are described, wherein X represents oxygen, sulfur, selenium or N-R9, wherein R9 represents hydrogen, an alkyl group, a hydroxyalkyl group, a phenyl group or an acetyl group; and the remaining R groups each represent variously hydrogen, hydroxy, amino, nitro, nitrile, alkyl, alkoxy, hydroxyalkyl, cyclic or aromatic groups, among others. Compositions for dyeing keratin fibers including a combination of coupler and developer substance are disclosed, in which the developer substance includes at least one of the new p-diaminobenzene derivative compounds.

摘要:
New substituted 2,5-diamino-1-aminomethylbenzene compounds of formula (I), or physiologically compatible water-soluble salts thereof, are described as well as methods for preparing them. In addition, oxidation dye precursor compositions for dyeing keratin fibers, especially human hair, which each contain from 0.005 to 20 percent by weight of at least one of the new substituted 2,5-diamino-1-aminomethylbenzene compounds of formula (I), or their physiologically compatible water-soluble salts, are described. Methods for dyeing hair with ready-to-apply dye mixtures made by mixing these oxidation dye precursor compositions with an oxidizing agent, such as hydrogen peroxide solution, are also described.
