<P>PROBLEM TO BE SOLVED: To eliminate the effect of excess fluorescence from a spectral sensitizer without lowering sensitivity, and to achieve excellent resolution (linearity) and printing durability. <P>SOLUTION: A photosensitive lithographic printing plate material is provided, which has on a support a photopolymerizable photosensitive layer comprising a photosensitive composition containing at least (A) a monomer containing an addition polymerizable ethylenic double bond, (B) a photopolymerization initiator and (C) a polymer binder, wherein a support on which the photosensitive composition is applied is treated with a solution containing a dye having an absorption maximum at a wavelength of 400-500 nm at a step after anodizing the support and before applying the photosensitive composition. <P>COPYRIGHT: (C)2007,JPO&INPIT |
