  The invention relates to the use of one or more N-substituted 2-pyrrolidone-4-carbonic acid esters of formula (1), where R1 and R2 independently represent linear, branched, or cyclic C1-C6 alkyl, as (a) solvent(s). Said compounds can be used as solvents in industrial applications, e.g. for the production of varnishes and paints, in chemical syntheses, for cleaning or degreasing, in petrochemical processes, in the electronics and photovoltaic industries, or in pesticide preparations, for example.

  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.
