Abstract: The present invention relates to a device (1) for dyeing keratin fibres, comprising at least two compartments (2) and (3), the first compartment (2) comprising a first composition (A) comprising oxidation dyes and the second compartment (3) comprising a second composition (B) comprising chemical oxidizing agents. Said device allows easy mixing of the compositions contained in said compartments at the time of use.

Abstract: The subject of the present invention is an aerosol device comprising a composition for dyeing keratin fibers, comprising at least one copolymer resulting from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and of at least one vinyl ester monomer, at least one fatty amine and at least one pigment. The invention also relates to a dyeing process wherein said composition is applied to keratin fibers, the operation optionally being followed by drying.

Abstract: 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.

Abstract: The present invention relates to a composition for dyeing keratin fibers, comprising at least (i) one or more copolymers derived from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and of at least one vinyl ester monomer, (ii) at least one silicone, the total amount of silicone(s) ranging from 0.1 % to 15% by weight relative to the total weight of the composition, and (iii) one or more pigments. The invention also relates to a dyeing process in which said composition is applied to keratin fibers, the operation optionally being followed by drying. The composition makes it possible to obtain temporary dyeing having the advantage of forming a transfer-resistant deposit, leaving the treated fibers individualized, with an improved cosmetic feel.
