Class Information
Number: 430/378
Name: Radiation imagery chemistry: process, composition, or product thereof > Color imaging process > Using identified radiation sensitive composition in the formation of color image > Silver compound sensitizer > And coupler > Direct positive process
Description: Processes for producing a direct positive color image. Included herein are processes involving radiation sensitive silver compound compositions which form direct positive images on exposure and development which images are used in the formation of color images. The unexposed portions rather than the exposed portions are developed during initial development. Also, processes involving couplers which react with oxidized developer in the exposed areas to form colorless products and which are oxidized in unexposed regions to form color images.
