Photosensitive, elastomeric compositions comprising (1) a high molecular weight carboxylated butadiene/acrylonitrile copolymer in which at least about 25% of the carboxyl groups are neutralized with a metal cation of Groups IIA or IIB of the Periodic Table, (2) an ethylenically unsaturated monomer, and (3) a free radical generating system, having outstanding properties as photosensitive elements for flexographic printing plates.
