PURPOSE:To obtain such a photosensitive flexographic printing plate that a high precision pattern can be formed, good workability such as printing durability, developing property, positioning property after plate making is obtd., and high printing accuracy with little fatigue of a developer is obtd., by successively depositing a transparent infusible layer which is insoluble with a developer and a photosensitive resin layer. CONSTITUTION:This plate consists of a supporting body, transparent infusible layer having elasticity which is insoluble with a developer, and photosensitive resin layer laminated in this order. The photosensitive resin layer consists of a photosensitive resin compsn. essentially comprising a polymer compd., photosensitive addition polymerizable ethylene-type unsatd. monomers, and photopolymn. initiator. The transparent infusible layer consists of a resin compsn. essentially comprising a binder, polyfunctional acrylate monomers, and photopolymn. initiator. Since each of the supporting body, transparent infusible layer and photosensitive resin layer is made of resin having high transparency, the transparency as the whole plate is made high so that good workability for positioning after plate making can be obtd. |
