COMPOSITION FOR COLOURING KERATINOUS MATERIAL USING A SUPRA-MOLECULAR COLOURING SYSTEM

摘要

The present invention relates to a composition for colouring keratinous materials. The composition contains in an appropriate medium at least one supra-molecular colouring system of the type (COLORANT)n(SAU)m (I), in which (COLORANT) is any chromophore having a maximal absorption of between 300 nm and 1200 nm covalently bonded to (SAU), and (SAU) represents an acceptor/donor radical capable of forming at least three hydrogen bonds. The invention provides a resistant and varied colouration of keratinous materials.
