ABSTRACT Photopolymerizable elements are described comprising a sheet support, a photopolymerizable layer having a thick- ness of, at most, 0.0006 inch (0.015 mm) and an optical density of at least 3.0 in the actinic region. Resist images made from these elements may be etched by a process of chemically undercutting the image areas and then spraying or rubbing them. The elements are useful as contact speed lithographic films and for other graphic arts applications.
