PURPOSE:To enhance photosensitivity and to widen development latitude by incorporating a compd. for generating an acid on irradiation of actinic rays, and a compd. having a silyl ether group decomposable with the acid and a hydrophilic group in the molecule. CONSTITUTION:An intended compsn. incorporates (a) a compd. capable of generating an acid on irradiation of actinic rays, such as o-quinonediazidesulfonyl chloride, (b) a compd, having at least one silyl ether group decomposable with the acid represented by formula I , and at least one hydrophilic group, such as a group represented by formula II, in the molecule, and said compd. (b) is such as a compd. represented by formula III in which R1 is an aliphatic or aromatic hydrocarbon group, and R4 is H, alkyl, alkenyl, aryl, or the like. The photosolubilizable compsn. contg. such compds. (a) and (b) can be used for a positive type photosensitive material, and since it has high sensitivity and wide development latitude, it is used for a lithographic plate, a print proofreading plate, etc. |
