Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Photographic processes or agents therefor; Regeneration of such processing agents > Diazo-type processes, e.g. thermal development, or agents therefor
CPC:
Photographic processes or agents therefor; Regeneration of such processing agents (multicolour processes or agents therefor G03C7/00; diffusion-transfer processes or agents therefor G03C8/00; stereo-photographic processes G03C9/00; photomechanical processes G03F) > Diazo-type processes, e.g. thermal development, or agents therefor
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
