This invention relates to a multilayered printing plate consisting of (1) a photosensitive printing layer comprising an elastomeric polymer, an ethylenically unsaturated monomer and a photoinitiator, (2) an elastomeric backing layer which is partially photocured and made from a vinyl terminated prepolymer containing a photoinitiator and (3) an optional supporting layer. The multilayer structure is useful for flexographic printing. |
