Zusammenfassung: | A process for producing a water development printing plate for relief printing, comprising providing a solid plate of photosensitive resin composition comprising at least (a) hydrophilic resin, (b) hydrophobic resin, (c) photopolymerizable unsaturated compound and (d) photopolymerization initiator and subjecting the solid plate to at least the steps of exposure to actinic rays, development and post-exposure. In the process, the post-exposure step is performed in an atmosphere of low oxygen concentration. |
