The invention relates to a composition for dyeing keratin materials, and in particular human keratin fibres such as the hair, comprising at least one 2-pyrrolidone functionalized in the 4 position with an ester or amide radical, and at least one hydrophobic direct dye or a pigment; a dyeing process using this composition. Similarly, the invention relates to the use of the said pyrrolidone combined with a direct dye or a pigment for dyeing keratin materials, and especially to the use of the said pyrrolidone for improving the colour uptake onto the fibres of direct dyes that are sparingly soluble or insoluble in aqueous-alcoholic supports. The invention also relates to novel pyrrolidone derivatives. The present invention makes it possible in particular to obtain direct dyeing on keratin materials that is fast, resistant to washing, chromatic and powerful.

The invention relates to the use of compounds derived from 2-pyrrolidone functionalized in position 4 with an ester, carboxylic acid or amide radical, for cosmetically treating keratin materials, especially for conditioning keratin materials, and in particular in terms of the disentangling, straightening, combability and manageability of human keratin fibres such as the hair. The invention also relates to novel cationic monopyrrolidone derivatives and to a cosmetic composition comprising them. Besides the suppleness of the keratin fibre, the compounds of formula (I) as defined previously also make it possible to improve the disentangling, straightening, combability and manageability of the head of hair; the shaping of the head of hair is easier, and the hair has a very pleasant, fluid feel.
