    摘要: A water soluble built-on mask layer is provided on a photoresist composition disposed on a substrate. The photoresist comprises an o-quinone diazide and a novolak or paravinyl phenol resin. The built-on mask layer comprises a water soluble, photobleachable diazonium salt, a coupler for the diazonium salt and an acidic, polymeric, film forming resin such as polystyrene sulfonic acid.

    摘要: A process for forming a multi-level positive working photosensitive element. One forms a composition containing an alkali soluble resin, an o-quinonediazide compound and an in-situ generated acid catalyzed crosslinker in a solvent mixture. After coating on a substrate, drying and partially cross-linking the first layer, a second positive working light sensitive layer is applied. Each light sensitive layer is activated by u.v. radiation in different parts of the spectrum. The top layer is imagewise exposed and developed to form a mask. The second layer is flood exposed through this mask and developed. Each development is conducted with an aqueous alkaline solution.
