Abstract
A photographic material which comprises a receiving element for transferred dyes is provided. The receiving element comprises a support having coated thereon a mordant layer which is made from a graft polymer prepared from gelatin, a monomer which when homopolymerized yields a water insoluble polymer and a monomer containing a sulphonate group which when homopolymerized yields a water soluble polymer. These receiving elements can be used for mordanting cationic dyes in photographic dye transfer processes.
