<p>The invention discloses a capillary dyeing composition comprising at least one direct dye, characterised in that it further contains a cross-linked polymer with acrylic and/or acrylate units and with acrylamide units. The invention also discloses the use of a cross-linked polymer with acrylic and/or acrylate units and with acrylamide units, in or for the production of a dyeing composition containing at least one direct dye, to improve the tinctorial power of the said composition, particularly after storage at below about 10 °C, and particularly at about 4 °C. The invention also discloses a method for preserving the tinctorial power, in particular after storage at a temperature below about 10° C, of a dyeing composition containing at least one direct dye, characterised in that an effective amount of the said cross-linked polymer is added to the composition.</p> |
