Abstract
Official abstract text for this publication.
An infrared radiation-sensitive positive-working imageable element has a substrate and single imageable layer that includes a first polymeric binder having urethane or urea moieties in its backbone. The first polymeric binder is also insoluble in water and soluble in a weakly alkaline solution. This imageable element can be imaged and processed using weakly alkaline processing solutions that are free of silicates and metasilicates, which processing solutions may also be used to “gum” the imaged and developed printing surface.
First claim
Opening claim text (preview).
The invention claimed is: 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 havin…
