DYE COMPOSITION BASED ON COPOLYMERS DERIVED FROM THE POLYMERIZATION OF AT LEAST ONE CROTONIC ACID MONOMER OR CROTONIC ACID DERIVATIVE AND ON SILICONE

The subject of the present invention relates to a composition for dyeing keratin fibers, comprising: a) one or more copolymer(s) derived from the polymerization of at least one monomer of crotonic acid or crotonic acid derivative and of at least one vinyl ester monomer, b) at least one oil-in-water emulsion having a particle size D 50 of less than 350 nm and which comprises: a silicone mixture comprising (i) at least one polydialkylsiloxane comprising trialkylsilyl end groups, having a viscosity at 25° C. ranging from 40 000 to 100 000 mPa·s and (ii) at least one aminosilicone having a viscosity at 25° C. ranging from 1000 to 15 000 mPa·s and an amine number ranging from 2 to 10 mg of KOH per gram of aminosilicone; a surfactant mixture comprising one or more nonionic surfactants, said mixture having an HLB ranging from 10 to 16, and water and c) at least one pigment.
