PHOTOPOLYMERIZABLE RECORDING MATERIALS, AND PHOTORESIS LAYERS AND FLAT PRINTING PLATES BASED ON THESE RECORDING MATERIALS, AND NEW CHINAZOLONE-4 COMPOUNDS

摘要

Photopolymerisable recording materials with at least one photopolymerisable, olefinically unsaturated organic compound, if appropriate a polymeric binder, a photopolymerisation initiator, a colour-forming system of a colour former and a photo-oxidising agent, a sensitiser and, if appropriate, further additives and/or auxiliaries contain certain quinazol-4-one compounds as sensitiser. …??These photopolymerisable recording materials are particularly suitable for producing photoresist layers and planographic printing plates.
