    • Disclosed herein is a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one oxidation dye and at least one polymer comprising a repetition of: (i) from 45 mol % to 60 mol % of at least one unit derived from a monomer of acrylamide type, (ii) at least one unit derived from a rnonomer of dialkyldiallylammonium halide type, and (iii) at least one unit derived from a monomer of vinylcarboxylic acid type, wherein the mole ratio of the amount of the at least one unit derived from a monomer of dialkyldiallylammonium halide type to the amount of the at least one unit derived from a monomer of vinylcarboxylic acid type is greater than or equal to 1. The composition disclosed herein makes it possible to prevent or reduce the phenomenon of static electricity at the surface of the hair, while at the same time maintaining good rheological and dyeing properties.
