ABSTRACT:
Certain synthetically prepared biopolymers are useful as peptizers in the preparation of photographic silver halide emulsions and elements. Such materials can be used as either nucleation or growth peptizers in place of common peptizing colloids, such as gelatins. The biopolymers can be prepared using recombinant or chemical synthetic methods and designed to have a particular affinity (either high or low) for silver ions. Thus, they can be used to control silver halide grain morphology in the emulsions.
