Claims19
A composition for dyeing keratin fibers, the composition in the form of a gel or cream and comprising:
- a) at least one oxidation dye precursor;
- b) at least one anionic associative polymer selected from the group consisting of acrylates/palmeth-25 acrylate copolymer, acrylate/palmeth-25 methacrylate copolymer, and mixtures thereof;
- c) at least one anionic non associative polymer chosen from those obtained from at least one monomer of formula (3) below:
- wherein:
- R′a represents a hydrogen atom or a linear or branched (C1-C6)alkyl group;
- R′c represents a hydrogen atom, a linear or branched (C1-C6)alkyl group, a C(O)OX group, or a -alk-C(O)OX group, wherein X represents a hydrogen atom, an alkali metal, alkaline earth metal, or ammonium and -alk- represents a (C1-C6)alkylene group;
- and R1 represents a hydrogen atom, an alkali metal, an alkaline metal, or a (C1-C6)alkyl group;
- d) at least one anionic surfactant;
- e) at least one alkaline agent comprising an alkanolamine, and
