杜邦公司研制的非银印刷制版片Crona-lite非银胶片,和高温快速加工显影机Crona-lisRAⅡ于81年1月开始在美国市场试销,81年6～7月自动显影机成批生产后,将在美国、日本同时正式出售。印刷制版和工业用感光材料,以前均以银为主要感光原料,杜邦公司研制的非银胶片,则以光固化性聚合物为感光层;涂布在聚酯片基上。该印刷制版片在显影加工中可不使用显影液和定影液,而仅用碱性Cronalite瞬时化学加工药液一次加工即可。过去,摄影完的胶片
DuPont developed non-silver printing plate Crona-lite non-silver film, and high-temperature rapid processing machine Crona-lisRA Ⅱ began in January 81 trial marketing in the United States, 81 June 6 ~ July automatic developer mass production, Will be officially sold in the United States, Japan at the same time. Printing plate and industrial photosensitive materials, formerly silver as the main photosensitive raw materials, DuPont developed non-silver film, the light-curable polymer as the photosensitive layer; coated on the polyester film base. The printing plate in the processing of the developer can not use the developer and fixing solution, but only with the basic chemical processing Cronalite instant chemical processing can be a single.
