Abstract: The present invention relates to an aerosol device comprising a composition for dyeing keratin fibres, comprising at least one aqueous dispersion of particles of hybrid, film-forming, hydrophobic acrylic polymer, at least one silicone compound chosen from linear silicone block copolymers and amino silicones, and at least one pigment. The invention also relates to a dyeing process in which said composition is applied to keratin fibres, the operation optionally being followed by drying. The composition makes it possible to obtain a coloured coating, which is persistent with respect to shampooing operations, leaving the treated fibres individualized, with an improved cosmetic feel.

Abstract: The present invention relates to a process for dyeing keratin fibres, in particular the hair, which consists in applying to a part of the keratin fibres, by means of a stencil, a composition comprising at least one hydrophobic film-forming polymer, at least one volatile solvent and at least one pigment, so as to form, after drying, a coloured pattern on the said fibres.

Abstract: The present invention relates to a process for treating keratin fibers, especially human keratin fibers such as the hair, using i) at least one triarylmethane or sulfonophthalein direct dye of formula (I) or (I′) as defined below, ii) an alkaline revealer, iii) an eraser at acidic pH. A subject of the invention is also a composition comprising at least one triarylmethane direct dye of formula (I) or (I′) as defined below and at least one thickener and/or at least one hydrotropic solvent, and a multi-compartment kit comprising i), ii) and iii) in three separate compartments. The present invention makes it possible in particular to obtain keratin fiber coloring with intense and persistent tints which can be modified, erased and reformed several times without any loss of color.
