PURPOSE:To obtain the entitled film balanced between densities of image and nonimage parts, by coating a support with a specified bubble forming compsn. CONSTITUTION:A coating soln. is obtained by dissolving in an org. solvent (e.g., toluene)(A) 2-20wt% photosensitive material (e.g., 4-morpho-lono-benzenediazonium salt) having absorption max. in 390-440nm wavelengths, (B) 0.1-3wt% dye (e.g., ''Diazine Blue J'') having absorption max. in 540-670nm wavelengths, and (C) 77-97.9wt% binder polymer having gas barrier action (e.g., acrylonitrile- vinylidene chloride coplymer). The transparent support is coated with said coating soln. and dried to form a 10-25mum thick coated layer having >=2.5 absorbance at the absorption max. point in 390-440nm, and 0.2-0.7 absorbance at the absorption max. point in 540-670nm. |
