<P>PROBLEM TO BE SOLVED: To obtain a flexographic printing original plate for newspaper printing which can be developed with an aqueous developer and has resistance to a water-based ink, such mechanical strength-ductility as to withstand high-speed printing, and good image reproducibility. <P>SOLUTION: A water-developable photosensitive resin laminate including a support and a photosensitive resin layer is used, wherein the support is a metal and the photosensitive resin layer has a mechanical strength-ductility property after photocuring of ≥80 kgf/cm<SP>2</SP>% and a water swelling rate of ≤8%. An adhesive layer containing an antihalation agent may be disposed between the support and the photosensitive resin layer, and the photosensitive resin layer may contain a hydrophobic polymer obtained from a water dispersion latex. <P>COPYRIGHT: (C)2007,JPO&INPIT |
