Waterless presensitized plate comprising four layers

A process for exposing a waterless presensitized plate to an image, said process comprising:

• contacting said plate with a computer controlled laser beam, said beam containing digitized information corresponding to said image, wherein said plate comprises a hydrophilic or non-hydrophilic solid substrate;
• a first layer on said substrate comprising an oleophilic photoadhesive coating containing an ethylenically unsaturated photopolymerizable monomer or oligomer having the property of adhesively polymerizing when exposed to actinic light or a photoreleasable adhesive coating containing quinonediazides having solubilizable properties upon exposure to actinic light;
• an actinic light transparent second layer comprising a solvent swellable, ink repellant silicone rubber;
• a third layer comprising a polymeric protective film essentially transparent to actinic light;
• and
• a fourth layer comprising a gelatino silver halide emulsion, said emulsion containing polymeric binders or keying agents to promote adhesion of said fourth layer to said protective film.
