It is superior in sharp Characteristic, super quick treatment possible halogenation silver photosensitive material

摘要

PURPOSE:To obtain images having high sharpness and high image quality by incorporating at least one kind of high-polymerized dyes formed by combining a water soluble high polymer and a water soluble dye having the specific max. absorption wavelength in an aq. soln. with each other into the under coating layer of a base. CONSTITUTION:At least one kind of the high-polymerized dyes formed by combining the water soluble high polymer and the water soluble dye having the max. absorption wavelength in an aq. soln. in a 400 to 1,000nm range with each other are incorporated into the under coating layer of the base. Namely, the incorporation of such high-polymerized dyes into the under coating layer is extremely easy, while the incorporation of dyes into the under coating layer is heretofore extremely difficult. The photosensitive material which has the high sharpness and is free from the possibility of after-colors or the degradation in sensitivity, etc., is obtd. in this way.
