Copolymer and silicone based dye composition obtained by polymerization of at least one crotonic acid monomer or crotonic acid derivative and at least one vinyl ester monomer, and method for dyeing keratin fiber using it
The present invention relates toComposition for dyeing keratin fiber(I) one or more copolymers obtained by polymerization of at least one crotonate monomer or crotonic acid derivative with at least one vinyl ester monomer(II) at least one siliconeAnd (III) one or more kinds of pigmentsIncluding at leastThe total amount of silicone isIt ranges from 0.1 mass% to 15% by mass to the total mass of the compositionIt relates to composition.The present invention also relates to a dyeing method in which the composition is applied to a keratin fiber and optionally dried after this operation.This composition forms a hard to migrate sediment and allows for temporarily stained dyeing with the advantage that one of the treated fibers is easy to glide and improved aesthetic.本発明は、ケラチン繊維を染色するための組成物であって、（ｉ）少なくとも１種のクロトン酸モノマー又はクロトン酸誘導体と少なくとも１種のビニルエステルモノマーとの重合により得られる１種又は複数種のコポリマー、（ｉｉ）少なくとも１種のシリコーン、及び（ｉｉｉ）１種又は複数種の顔料、を少なくとも含み、シリコーンの総量は、組成物の総質量に対し０．１質量％～１５質量％の範囲にある、組成物に関する。本発明はまた、前記組成物をケラチン繊維に適用し、この操作の後に任意選択で乾燥を行う、染色方法にも関する。この組成物は、色移りし難い堆積物を形成し、処理された繊維は１本１本がばらけ易く、美的感触が向上しているという利点を有する、一時染色を行うことを可能にする。
