G03C PHOTOSENSITIVE MATERIALS FOR PHOTOGRAPHIC PURPOSES (for photomechanical purposes G03F); PHOTOGRAPHIC PROCESSES, e.g. CINE, X-RAY, COLOUR, STEREO-PHOTOGRAPHIC PROCESSES; AUXILIARY PROCESSES IN PHOTOGRAPHY (photographic processes characterised by the use or manipulation of apparatus classifiable per se in subclass G03B, see G03B; photomechanical production of textured or patterned surfaces G03F; electrophotography, magnetography G03G)
Introduced: September 1968
Description
G03C covers photographic films, plates, papers, and emulsions designed to capture and record images through light exposure, including silver halide and other light-sensitive compositions. This subclass encompasses conventional color, black-and-white, X-ray, cinematographic, and stereoscopic photographic processes, as well as auxiliary techniques such as image development, fixing, sensitization, and post-exposure treatments. The classification extends to photosensitive layers, coating methods, and chemical formulations that enable photographic image formation across various media and applications. Related optical and digital imaging technologies are excluded; see G03B for photographic apparatus and G03F for photomechanical processes.
