Abstract
A layer of a liquid composition containing a residue that is polymerizable on contact with a gaseous polymerizing agent and a photocurable residue, which residues may be on the same or different molecules, is contained with a gaseous polymerizing agent so that the layer solidifies but remains photocurable. Subsequently the 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 polymerizable residues include cyanoacrylates that polymerize on exposure to water vapor, ammonia, or an amine. Typical photocurable residues include acrylates, and methacrylates. The process is suitable for the manufacture of printing plates and printed circuits.
