NEGATIVE-WORKING ON-PRESS DEVELOPABLE IMAGEABLE ELEMENTS

摘要

Negative-working imageable elements can be imaged and processed on-press to provide lithographic printing plates, especially with sulfuric acid-anodized aluminum substrates. These elements have an imageable layer that contains two different polymeric binders, a first polymeric binder that is present a discrete particles, and a second polymeric binder that comprises pendant ethylenically unsaturated groups.
