DEFINITION

Classification: 430/217

Silver halide identified-grain, identified emulsion binder other than nominal gelatin, or identified sensitizer or identified desensitizer containing:

(under subclass 212) Element containing a silver halide identified grain of specified form, e.g., size, crystal habit, etc., or a silver halide identified binder other than a nominal gelatin or a silver halide identified ingredient which performs the function of, e.g., hypersensitizing, latensifying, optical sensitizing or desensitizing, etc.
