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: Hydrophilic coupler solutions are improved by the addition of a diepoxide, pyruvaldehyde, ethyleneglycoldiglycidyl ether or 2,3-butanedione. These solutions exhibit greater stability and a reduced rate of viscosity increase when admixed into gelatin silver halide emulsions.

摘要: Hydrophilic coupler-oil solutions are stabilized by the addition of an epoxide compound. These coupler compounds are dissolved, with the aid of epoxide compounds, in high boiling esters and dispersed in aqueous gel solutions to form dispersions of improved stability.
摘要翻译: 通过加入环氧化合物使亲水性成色剂 - 油溶液稳定。 这些成色剂化合物借助于环氧化合物在高沸点酯中溶解并分散在水性凝胶溶液中以形成稳定性提高的分散体。
