Abstract (en)
[origin: US4810628A] In a heat developable color photographic recording material containing, in a common layer of binder, a light-sensitive silver halide, optionally combined with a substantially light-sensitive silver salt, and a non-diffusible dye releasing compound, the binder of the said layer consists to an extent of at least 30% by weight of a polyurethane containing anionic groups. The recording material has a considerably increased sensitivity combined with improved Dmin/Dmax relationship.
