Ultraviolet-sensitive photographic materials - based on acidic cellulose ether(s) or ester(s)

摘要

Photographic materials comprise a light-sensitive cellulose deriv. (I) selected from acidic cellulose ethers and esthers their copolymers with synthetic monomers. The materials can be used to produce outline or halftone images, e.g. of engineering drawings or advertisements, in UV light without interference from scattered visible light. They have good thermal, chemical and storage stability, and produce images with good resolution and contrast.
