ABSTRACT:
A photosensitive resin composition for flexographic printing plates comprising styrene-butadiene block copolymer containing 35 - 50% by weight of styrene, at least one liquid prepolymer having a molecular weight of 1,000 - 5,000 selected from the group consisting of polybutadiene and butadiene-styrene copolymer, at least one photopolymerizable monomer containing at least one vinyl group, such as tetraethyleneglycol diacrylate, a photopolymerization initiator such as benzophenone, and a thermopolymerization inhibitor optionally added. This photosensitive resin composition affords relief images suitable for use in flexographic printing.
