DIFF Subgroup
G03C 1/76 Photosensitive materials characterised by the base or auxiliary layers
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Photosensitive materials > Photosensitive materials characterised by the base or auxiliary layers
CPC:
Photosensitive materials (photosensitive materials for multicolour processes G03C7/00; for diffusion transfer processes G03C8/00; photosensitive glass C03C4/04) > Photosensitive materials characterised by the base or auxiliary layers
Of 14 combined children, 11 exist in both systems.
3 codes are CPC-only extensions.
Note: 1 CPC extensions are marked as secondary classification only.
5 shared codes have differing titles between IPC and CPC.
