Abstract
A photosensitive resin composition includes a urethane oligomer prepared from a hydroxy-functionalized acrylate and/or methacrylate, at least one diol, and 2,4-toluene diisocyanate and 2,6-toluene diisocyanate in a 65:35 weight ratio. The resin composition additionally contains a monomer having at least one acrylate or methacrylate group, and a photoreactive initiator. The photosensitive resin composition may be cured to provide a soft photopolymer printing plate, particularly well suited for printing on corrugated bard.
