Abstract
A negative-working photosensitive material having formed on a support a photopolymerizable layer containing an addition polymerizable compound having at least one ethylenically unsaturated double bond, a photopolymerization initiator, and a high molecular weight binder and also having formed on the layer a protective layer containing a water-soluble vinyl polymer and a polymer which does not have a compatibility with polyvinyl alcohol and is water soluble in itself. The protective layer has a practically sufficient adhesive property to the photopolymerizable layer and the photosensitive layer has a high sensitivity to an Ar.sup.+ laser and a TAG-SHG laser and is suitably used as a photosensitive lithographic printing plate.
