Enhanced durability printing plates and method of making

摘要

A metal substrate printing plate is provided comprising a surface layer of a photosensitive composition containing azide compound, an IR sensitive dye, a crosslinkable polymer resin and an adhesion promoting resin that is put through a post thermal process during the manufacturing of the plate. This special thermal treatment allows for improved mechanical and chemical resistance as well as affording run lengths up to one million impressions after imaging and processing.
