Full Title

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 more than one photosensitive layer (G03F7/075 takes precedence)
