摘要:The present teachings relate to a composition comprising a functionalised dye and a diallylamine comonomer, and the use of such compositions in methods of colouring a substrate. The present teachings provide improved bonding of a dye to a substrate, and preferably allow colouring to be conducted entirely in the presence of an aqueous solvent.
