ABSTRACT:
Photosensitive elements comprising a layer of a solvent-soluble, thermoplastic, elastomeric, block copolymer, a nongaseous ethylenically unsaturated compound, and an addition polymerization initiator activatable by actinic light interposed between a support and cover sheet, a flexible polymeric film, e.g., polyamide, being interposed between the cover sheet and the surface of the layer. The elements are useful in preparing printing plates, particularly flexographic printing plates, and other relief images.
