<p>PROCESS FOR THE PRODUCTION OF IMAGES A polymerising agent is applied to a substrate followed by a layer of a liquid composition containing both a polymerisable residue and a photocurable residue. The polymerisable residue is polymerised by the polymerising agent first applied so that the layer solidifies but remains photocurable. Subsequently this solidified layer is exposed to actinic radiation in a predetermined pattern and those parts of the layer that are not photocured are removed by treatment with a suitable solvent. Typical polymerisable residues include cyanoacrylates, the polymerising agents for which may be water, ammonium hydrides solution, an alkali metal hydroxide solution, or an amine. Typical photocurable residues include acrylates and methacrylates, : The process is suitable for the manufacture of printing plates and printed circuits,</p> |
