Abstract

PURPOSE:To obtain a visible image which is easily identified even under yellow safelight at the time of exposure, by incorporating a compd. which generates an acid on being irradiated with active rays, a compd. which can be decomposed by the acid, a specified alkali-soluble resin and a sulfophthalein dye. CONSTITUTION:A compd. which can generate an acid on being irradiated with active rays, a compd. which can be decomposed by the acid, an alkali-soluble resin and a sulfophthalein dye represented by formula I are incorporated into a photosensitive compsn. When 1pt.vol. of 6wt.% soln. of the alkali-soluble resin in methylcellosolve is diluted with 10pts.vol. of a mixed solvent consisting of methanol and water in 1:1 ratio, the diluted soln. has 5.0-10.0 pH at 25 deg.C. In formula I, each of A1-A4 is H or halogen and each of R1-R4 and R1'-R4' is H, halogen or lower alkyl. The resulting photosensitive compsn. is adapted for a photosensitive planographic printing plate giving a high contrast visible image which is easily identified even under yellow safelight at the time of exposure.
