Abstract
Flexographic printing plates are prepared from photosensitive elastomeric compositions which comprise PA0 (1) about 15 to about 89 percent by weight of a carbamated poly(vinyl alcohol) polymeric binder, PA0 (2) about 10 to about 70 percent by weight of a compatible monomer, and PA0 (3) about 0.1 to about 10 percent by weight of a free-radical generating system.
