(A) is present in the form of lotion, aerosol foam, (after) shampoo, gel, wax or present in a pressurized or aerosol spray bottle. (A) further comprises a nucleophilic agent i.e. present within (A) or conditioned separately. Preferred Method: The hair coloring method comprises a pre-treatment of the hair with the nucleophilic agent. #CMT#POLYMERS : #/CMT# Preferred Components: (I) is of formula (R1)(R2)C=C(CN)(COXR3a). (I) is covalently bound on a support such as polymers, oligomers or dendrimers. (I) is present in the composition at 0.1-80 wt.%, preferably 2-20 wt.%.
