Photoconductive layers characterised by having two or more layers or characterised by their composite structure

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Recording-members for original recording by exposure, e.g. to light, to heat or to electrons; Manufacture thereof; Selection of materials therefor > Charge-receiving layers > Photoconductive layers; Charge-generation layers or charge-transporting layers; Additives therefor; Binders therefor > Photoconductive layers characterised by having two or more layers or characterised by their composite structure

CPC:

Recording-members for original recording by exposure, e.g. to light, to heat or to electrons; Manufacture thereof; Selection of materials therefor > Charge-receiving layers (G03G5/153 takes precedence) > Photoconductive layers; Charge-generation layers or charge-transporting layers; Additives therefor; Binders therefor > Photoconductive layers characterised by having two or more layers or characterised by their composite structure

CPC subdivides this area 3x more granularly than IPC with 2 additional codes.

2 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
