Abstract: The present invention relates to a novel dyeing composition suitable for dyeing leather, hides and/or pelts comprising at least one dyeing agent and at least one polycarbodiimide agent and optionally water-miscible organic solvent and/or optionally one or more plasticizer and/or optionally one or more dispersing agents and/or optionally one or more acidifying agents, to obtain leather that has good colour fastness according to ISO 11640:2012 and good lightfastness according to ISO 105-B02 and/or to IUF 402 and that results in an outstanding uniform colouring throughout the leather.
