Abstract
A photopolymerizable coating over a diazo resin provides a high-speed lithographic plate or photoresist while improving the printing life of the plate while making its development simpler than that of most other photopolymer plates. The photopolymer is a cinnamoylated polyvinyl alcohol resin which is placed over a diazo based material.
