Full titles differ between systems:

IPC:

CPC:

Photosensitive materials (photosensitive materials for multicolour processes G03C7/00; for diffusion transfer processes G03C8/00; photosensitive glass C03C4/04) > Silver halide emulsions; Preparation thereof; Physical treatment thereof; Incorporation of additives therein (catalytic amounts of silver halide in dry silver systems G03C1/494) > with non-macromolecular additives (G03C1/047 takes precedence; ) > Sensitivity-increasing substances

CPC subdivides this area 4x more granularly than IPC with 10 additional codes.

10 codes are CPC-only extensions.
