Abstract
Photographic processing compositions containing a light-reflecting pigment and a styrene-butadiene copolymer are disclosed. The photographic processing compositions are useful in photographic diffusion transfer film units and processes for the provision of permanent photographic laminates. A light-reflecting layer formed in a photographic laminate from such a processing composition exhibits a reduced tendency toward cohesion or adhesion failure and separation.
