Abstract

The invention relates to an oxidation dye composition for keratin fibres, in particular for human keratin fibres such as hair, of the type comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and optionally one or more couplers, and which is characterized in that it contains (i) as oxidation dye precursor, at least one para-phenylenediamine substituted in the 2-position on the benzene ring with a C1-C4 hydroxyalkyl or hydroxyalkoxy radical, and/or at least one of the addition salts thereof with an acid, and (ii) at least one cationic or amphoteric substantive polymer. The invention also relates to the use of this composition for dyeing keratin fibres, especially hair.

Dependent claims

An oxidation dye composition for keratin fibres, comprising, in a medium appropriate for dyeing,

at least one oxidation dye precursor, at least one coupler, and at least one cationic or amphoteric substantive polymer;
said at least one oxidation dye precursor being selected from para-phenylenediamines of formula (I):
in which m is an integer equal to zero, and n is an integer ranging from 1 to 4, or an acid addition salt thereof;
and said at least one cationic or amphoteric substantive polymer, being selected from:
(i) a copolymer of dimethyldiallylammonium chloride and acrylamide;
(ii) a quaternary polyammonium polymer consisting of repeating units of formula (II):
wherein said polymer has a molecular weight, determined by gel permeation chromatography, which ranges from 9500 to 9900;
(iii) a quaternary polyammonium polymer consisting of repeating units of formula (III):
wherein said polymer has a molecular weight, determined by gel permeation chromatography, which ranges from 1080 to 1320;
(iv) a quaternary polyammonium polymer consisting of repeating units of formula (IV):
in which p represents an integer ranging from 1 to 6;
D may be nonexistent or may represent a group (CH2)r—CO— in which r represents a number equal to 4 or 7, and wherein said polymer has a molecular weight, determined by gel permeation chromatography, of less than 100,000;
or
(v) a copolymer of diallyldimethylammonium chloride and acrylic acid.
