摘要:
This invention is directed to oxidation hair dye compositions and their use in the dyeing of human hair. The compositions consist essentially of precursors comprising 2,3-diamino-6-methoxy-pyridines and aromatic amines or diamines. The combination of oxidation dye precursors according to the invention gives bright, deep blue dye finishes having high stability to heat and light.
