ABSTRACT:
The present invention is concerned with a photosensitive polymer composition for a water-developable, flexographic printing plate, having a phase separating structure in a sea-and-islands state, the phase separating structure comprising island phases and a sea phase, the island phase comprising a thermoplastic elastomer component having a glass transition temperature lower than 25.degree. C., and the sea phase comprising a gelled, ethylenically unsaturated compound component.
The photosensitive polymer composition of the present invention affords a printing plate capable of being developed with neutral water and suitable for flexographic printing using a water-based ink.
