DEVELOPING SOLUTION FOR COLORED IMAGE FORMING MATERIAL

摘要

PURPOSE:To enable stable processing for a long period without causing precipitation even at the time of a lot of colored image forming material by incorporating a chelating agent and a basic compound and water in the developing solution. CONSTITUTION:This developing solution is used for developing the colored image-forming material provided on a transparent substrate treated to enhance releasabilty with a colored photosensitive layer containing a photosensitive composition and a colorant, and the developing solution contains the basic compound in such an amount as holding pH of the developing solution in the range of 10-13.5 and the chelating agent and water, thus permitting stable processing to be ensured without causing precipitation even when a large amount of colored image-forming materials are processed.
