PURPOSE:To attain the improvement to remove the non-exposed and non-cured photosensitive layer of a photosensitive material and to prevent the generation of printing stains in the non-image part by constituting the compsn. of an aq. soln. contg. a specific compd. CONSTITUTION:The photosetting photosensitive layer is provided and said layer is constituted of the aq. soln. contg. the compd. expressed by formula I. In formula I, R1 denotes a hydrogen atom, halogen atom, etc.; R2 denotes a hydrogen atom, alkyl group, etc.; R3 denotes a hydrogen atom or alkyl group of 1-2C; (m), (n) denote 1-3 integer. The content of the compd. expressed by formula I is confined to a 1-20wt.% range in the developing soln. compsn. The non-exposed part is thereby completely removed and the removing rate is improved; in addition, the generation of the printing stains in the non-image part is prevented. |
