DIFF Subgroup
G03C 1/494 Silver salt compositions other than silver halide emulsions; Photothermographic systems
Introduced: January 1990
Full Title
Full titles differ between systems:
IPC:
Photosensitive materials > Silver salt compositions other than silver halide emulsions; Photothermographic systems
CPC:
Photosensitive materials (photosensitive materials for multicolour processes G03C7/00; for diffusion transfer processes G03C8/00; photosensitive glass C03C4/04) > Silver salt compositions other than silver halide emulsions; Photothermographic systems
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1990.
