Abstract:
1. A method of providing an image comprising: A) using a laser, imagewise exposing an imageable element to provide an exposed element having exposed and non-exposed regions, and B) contacting said exposed element with an alkaline processing solution having a pH of 12 or less to remove predominantly only said exposed regions, wherein the imageable element is an infrared radiation-sensitive positive-working imageable element comprising a substrate having thereon a single imageable layer, wherein said first polymeric binder is present in said imageable layer in an amount of at least 50 weight % based on said layer solids, and the alkaline processing solution is a single phase solution and has from about 0.5 to about 15 weight % of an organic solvent and is free of silicates and metasilicates, wherein the organic solvent is selected from the group consisting of (a) reaction products of phenol with ethylene oxide or with propylene oxide, (b) benzyl alcohol, (c) esters of ethylene glycol or of propylene glycol with an acid having 6 or less carbon atoms, (d) ethers of ethylene glycol, diethylene glycol, or of propylene glycol with alkyl groups having 6 or less carbon atoms, (e) and mixtures thereof.
