PURPOSE:To obtain the above copying material capable of conducting the long time maintenance of the processing capacity of a developer and produces a waste liquid in a lesser amt. by removing org. coating layers by a washing stage. CONSTITUTION:The photosensitive copying material successively having the 1st photosensitive org. coating layer which is changed in solubility by photoirradiation and the 2nd org. coating layer contg. a water insoluble and org. solvent soluble high-polymer compd. having film formability on a base is subjected to development processing after image exposing. The 2nd org. coating layer of the non-image parts is removed in the washing stage after immersion in the developer in this method. |
