Abstract (en)
[origin: WO2020229099A1] The present invention relates to a method for dyeing keratinous material, in particular human hair, comprising the following steps: - applying an agent (a) to the keratinous material, said agent (a) containing: (a1) at least one organic silicon compound from the group comprising silanes with one, two or three silicon atoms; and (a2) at least one first chromophoric compound from the group comprising pigments and/or direct dyes; and - applying an agent (b) to the keratinous material, said agent (b) containing: (b1) at least one film-forming polymer, containing a copolymer that has at least one structural unit of formula (i) and at least one structural unit of formula (ii) wherein R1 represents a (C1 to C18) alkyl group, - and M1 and M2 independently represent a hydrogen atom, a (C1 to C6) alkyl group or an equivalent of a mono- or polyvalent cation.
