ABSTRACT:
An elastomeric article suitable for flexographic printing comprising an elastomeric natural or synthetic dienoid polymer or copolymer, a photopolymerizable, ethylenically unsaturated crosslinking agent and a photoinitiator, portions of said article having been exposed to a photopolymerizable-effective amount of actinic radiation through an image bearing transparency having clear and opaque areas, and processed to remove the soluble portion of said plate situated beneath the opaque areas of the transparency during exposure, and said processed plate having been treated with iodine so as to render its printing surface tack-free and resistant to hardening when further exposed to actinic radiation.
