Macromolecular quinonediazides; Macromolecular additives, e.g. binders

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 > Quinonediazides > Macromolecular quinonediazides; Macromolecular additives, e.g. binders

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) > Quinonediazides (G03F7/075 takes precedence) > Macromolecular quinonediazides; Macromolecular additives, e.g. binders
