Abstract: The process for dyeing leather by the exhaust method comprises allowing a pigment dispersion and an aqueous solution of sulfur dye to act on the conventionally pretreated leather in one step or in succession. It affords a high depth of shade and a high brilliance which are not achieved by using the pigment or the sulfur dye on its own.
