Process for the production images using sequentially gaseous polymerizing agents and photocuring
First Claim
1. A process for the production of an image which comprises(a) applying to a substrate a layer of a liquid composition containing a residue that is polymerizable on contact with a gaseous polymerizing agent, and a photocurable residue,(b) contacting the composition with a gaseous polymerizing agent such that the layer solidifies but remains photocurable,(c) exposing the solidified layer to actinic radiation in a predetermined pattern such that exposed parts of the layer are photocured, and(d) removing those parts of the layer which have not become substantially photocured by treatment with a solvent therefor.

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.
