ABSTRACT:
A photosensitive recording material comprising (a) a substrate having a hydrophilic surface, (b) an undercoating layer comprising at least one compound having at least one functional group selected from the group consisting of thiol, thioether and disulfide groups, and (c) a photosensitive layer comprising at least one diazonium compound and a high molecular weight binder compound which is insoluble in water and soluble in aqueous alkaline solution. The resulting developed plate yields no background contamination in printing process.
