Abstract

1,189,944. Developing photo-polymerizable materials. E.I. DU PONT DE NEMOURS & CO. Jan.16, 1968, No.2392/68. Addition to 1,148,362. Heading G2C. An aqueous developer for exposed photopolymerizable layers comprises crater, 1-50% by volume of at least one organic solvent selected from 2-butoxyethanol, diacetone alcohol and ethyl acetate based on the volume of the developer and at least one water-soluble organic or inorganic base material, the pH being 8-13. The base material may be an alkali metal phosphate buffer, borax, sodium hydroxide, carbonate or bicarbonate or ammonium hydroxide. In the examples, a photo-polymerizable layer containing penta-erythritol triacrylate, a methyl methacrylate/methacrylic acid copolymer and an anthraquinone initiator is overcoated with a polyvinyl alcohol layer, imagewise exposed and developed with an aqueous solution containing sodium or ammonium hydroxide, trisodium or sodium dihydrogen phosphate, sodium hexametaphosphate, sodium carbonate or an organic amine as alkali and 2-(butoxy or ethoxy) ethanol, acetone, diacetone alcohol, ethyl acetate or methanol, ethanol or isopropyl alcohol as organic solvent. The developer may also contain a surfactant, polyethylene glycol, a sequestering agent or potassium bichromate.
