DEFINITION

Classification: 430/617

Silver compound other than halide, per se, or composition for thermos:graphic process:

(under subclass 564) Products containing a silver compound other than a silver halide, per se, i.e., a silver containing product other than a silver and a halogen atom, e.g., silver nitrate, silver chlorate, etc., or intended for use as the radiation sensitive composition or element in a thermos:graphic process, i.e., a process classified in this class, subclass 198 or 348.

(1) Note. The classification of a composition which is prepared by the reaction of a nonhalide silver compound in greater than equimolar quantity with a halide containing salt to produce a composition containing light sensitive silver halide along with the unreacted nonhalide silver compound is as follows: If no mention is made as to the extent of reaction it is assumed that the patentee is primarily concerned with producing a silver halide rather than a mixture and that reaction is complete. In such a situation, classification is made on the basis of the halide. Classification in this subclass is proper when a statement is present in the disclosure as to the extent of reaction and/or it is apparent from the total disclosure that the patentee is concerned primarily with preparing a composition composed of a silver compound and a nonhalide silver containing compound.

(2) Note. The radiation sensitive product contains at least one radiation sensitive silver compound.
