Abstract

A photoreactive coating composition, particularly suited for use in a lithographic plate, is characterized by both reduced exposure time requirements and an intense visual image which is immediately produced upon exposure of the composition to light permitting visual inspection during imaging. The photoreactive composition has a diazo resin layer and an overlayer which includes a photochromic compound (e.g. an indolinobenzospiropyran compound) and a light sensitive polymer selected from the group cinnamoylated and acrylated photopolymer resins.
