Photographic processing compositions comprising an aqueous alkaline medium and a hydrophobically modified thickening agent are disclosed. The subject thickening agent increases the viscosity of the processing composition while maintaining a relatively uniform homogenous mixture of the constituents thereof. The subject processing compositions are useful in photographic diffusion transfer film units and processes.
