Abstract

Light-sensitive positive-acting layer comprises 4- and/or 5-substd. diazo resin, polymeric resin and hindered phenol or polyphenol having a mol.wt. higher than 108. Processed for obtaining negative and positive images are also claimed. Pref. (a) Negative image: process comprises imagewise exposing through an original, material contg. a light-sensitive layer as claimed, heating it to render the exposed portion alkali-insol., cooling it, totally exposing it to light and developing it with an alkaline developer; (b) Positive image: process comprises imagewise exposing, through an original, a material contg. a light-sensitive layer as claimed and developing it with an alkaline developer.
