DEVICE FOR APPLYING A COMPOSITION FOR DYEING KERATIN FIBRES, COMPRISING AT LEAST ONE COPOLYMER DERIVED FROM THE POLYMERIZATION OF AT LEAST ONE MONOMER OF CROTONIC ACID OR CROTONIC ACID DERIVATIVE

摘要

A device (1) for applying a composition for dyeing keratin fibres, especially the hair, comprises a container (2) comprising a body (9) forming a reservoir intended to contain the composition for dyeing keratin fibres, said composition comprising at least one copolymer derived from the polymerization of at least one monomer of crotonic acid or crotonic acid derivative and of at least one vinyl ester monomer, at least one thickening polymer containing (meth)acrylic acid units, and at least one pigment. The device (1) also comprises an applicator (3) for applying said composition to the keratin fibres.
