PROBLEM TO BE SOLVED: To provide a highly sensitive and highly plate-wearable original plate for lithographic printing, by which scanning exposures based on digital signals is possible and which has a favorable on-machine developability. SOLUTION: The original plate for lithographic printing has an image forming layer, which includes at least one component selected from the group consisting of fine particles including a compound having an epoxy group and microcapsules containing a compound having an epoxy group, a hydrophilic resin and an acid precursor, on a hydrophilic support and can be developed on a printer. |
