ABSTRACT:
A layered sheet construction suitable after processing for use as a relief printing plate is provided. The sheet is made of a photosensitive layer comprising an elastomeric polymer, between about 5 and 30 phr of an ethylenically unsaturated compound and between 0.1 and 5 phr of a photoinitiator activatable by actinic radiation; a base layer immediately adjacent to said photosensitive layer capable of supporting a relief image after processing; having the same or a different composition than said photosensitive layer. The sheet is bonded to an open or closed cell foam layer having a thickness between about 0.010 inch and 0.250 inch. Said foam has a recovery rate of at least 80%, a compression value between about 0.003 inch and 0.030 inch and a density of between about 2 to 50 lbs/ft.sup.3 and is bonded to a dimensionally stable supporting layer.
