ABSTRACT:
A method of coloring porous material, especially human hair, is described, which method comprises applying to the material being colored, in any desired order successively, or simultaneously, a) a capped diazonium compound and b) a water-soluble coupling component under conditions such that, initially, coupling does not take place, and then causing the capped diazonium compound present on the material to react with the coupling component.
