摘要:
Some novel diazo compounds, and salts thereof, useful for dyeing keratinous fibers, particularly human hair are disclosed. Illustrative of these compounds are the methyl sulfate salts of 1'-(4'-N,N-dimethylaminobenzene) 2-azo 4-cyano 1-methyl pyridinium methyl sulfate and 1'-(4'-amino 8'-hydroxy naphthalene) 2-azo 1-methyl pyridinium. Hair setting lotions, hair dye compositions and hair lacquers containing these compounds, preferably in alcoholic solutions, are also disclosed.

Indoaniline having the formula ##SPC1##Wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represent a member selected from the group consisting of hydrogen, lower alkyl or halogen with 1 - 2 of these substituents being other than hydrogen; R.sub.5, R.sub.6 and R.sub.7 each independently represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkoxy; R.sub.8 and R.sub.9 each independently represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkyl substituted with a member selected from the group consisting of amino, hydroxy, carbamoyl, piperidinyl and acylamino, R.sub.8 and R.sub.5 or R.sub.9 and R.sub.6 being able to form with the adjacent nitrogen atom a dihydro-oxazine or pyrroline heterocycle; Z represents a member selected from the group consisting of amino, acylamino and hydroxy, and the salts formed by these indoanilines with organic or inorganic acids, in particular, their acetates, oxalates, hydrochlorides, hydrobromides, persulfates, perchlorates and the double zinc salts of these compounds, which can, of course, be in a tautomeric form of that represented by the above formula. These indoanilines are usefully employed for dyeing keratinous fibers, and, in particular, human hair.

摘要:
There are described dyeing compositions for keratin fibres, and in particular for human hair, containing a dyestuff of the formula: ##STR1## in which A denotes an alkylene group, an alkylene group substituted by one or more OH groups, or an alkylene group interrupted by a hetero-atom such as oxygen or by an --NH-- group, R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, or R.sub.1 and R.sub.2 can together form a heterocyclic ring chosen from among piperidino or morpholino groups, Y denotes alkoxy or NO.sub.2, R denotes hydrogen or lower alkyl, and if Y denotes alkoxy, Z denotes NO.sub.2 and is located in the para-position to the amine group, and if Y denotes NO.sub.2, (a) Z denotes alkoxy or OH and is located in the para-position to the NO.sub.2 group, or alternatively (b) Z denotes OH and is located in the para-position to the amine group, and also their cosmetically acceptable salts. Many of these dyestuff are novel.
摘要:
Compounds having the general formula: ##STR1## in which R denotes hydrogen, a lower alkyl, lower hydroxyalkyl or lower polyhydroxyalkyl radical or alternatively an alkyl, hydroxyalkyl or polyhydroxyalkyl radical in which the alkyl chain is interrupted by one or more hetero-atoms such as oxygen are described. These compounds can be used in dyeing compositions for keratin fibres and wavesetting lotions. They make it possible to obtain very strong shades.

New-meta-phenylenediamines are described for use in dyeing keratin fibres, especially human hair. These have the general formula: ##STR1## in which R represents an alkyl radical containing from 1 to 4 carbon atoms and n is an integer of from 1 to 3, or an acid salt thereof from 1 to 3 and include their acid salts.
摘要:
Novel compounds of the general formula ##STR1## wherein Z represents a substituted lower alkyl radical; each of R.sub.1 and R.sub.2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO.sub.2 and NR.sub.1 R.sub.2 can occupy all ring positions in relation to OZ, with the exception that if Z is .beta.-hydroxyethyl, --NO.sub.2 is in the 4 position and --N(R.sub.1)(R.sub.2) is in the 2 position then either R.sub.1 or R.sub.2 is other than hydrogen.The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.
