having cover layers or intermediate layers, e.g. subbing layers

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Photomechanical, e.g. photolithographic, production of textured or patterned surfaces, e.g. printed surfaces; Materials therefor, e.g. comprising photoresists; Apparatus specially adapted therefor > Photosensitive materials > characterised by structural details, e.g. supports, auxiliary layers > having cover layers or intermediate layers, e.g. subbing layers

CPC:

Photomechanical, e.g. photolithographic, production of textured or patterned surfaces, e.g. printing surfaces; Materials therefor, e.g. comprising photoresists; Apparatus specially adapted therefor (using photoresist structures for special production processes, see the relevant places, e.g. B44C, H10P76/00, H05K) > Photosensitive materials (G03F7/12, G03F7/14 take precedence) > characterised by structural details, e.g. supports, auxiliary layers (supports for printing plates in general B41N) > having cover layers or intermediate layers, e.g. subbing layers
