DEFINITION

Classification: 430/230

Identified silver halide grain, silver halide emulsion, binder other than nominally defined gelatin, or silver halide sensitizer or desensitizer containing:

(under subclass 227) Subject matter containing a radiation sensitive silver halide layer having silver halide grains of a specified form, e.g., size, crystal habit, etc., containing an identified silver halide binder other than broadly defined gelatin, or containing an identified sensitizing, e.g., optical, latensifying, or desensitizing ingredient.
