  Various embodiments relate to biorenewable and water-degradable co-polymers and methods of producing co-polymers that include a plurality of first monomeric units and a plurality of second monomeric units joined by a plurality of hydrolytically-sensitive ester linkages. Each of the plurality of first monomeric units may be derived from a first monomer. The first monomer may be the product of a reaction between itaconic acid and a first amino acid. Each of the plurality of second monomeric units may be derived from a second monomer. The second monomer may be the product of a reaction between itaconic acid and a second amino acid. The co-polymers may be a product of the reaction of the first monomer and the second monomer in the presence of a diol. The co-polymers may have a glass transition temperature of about 50° C. or greater.

  The invention relates to a composition for dyeing keratin fibres, and in particular human keratin fibres such as the hair, comprising at least one 2-pyrrolidone functionalized in the 4 position with a carboxylic acid 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 fibres, 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 fibres that is fast, resistant to washing, chromatic and powerful.
