    Abstract: A photoreactive composition containing an effective amount of a compound having at least two alkoxyaromaticglyoxy substituents per molecule, which substituents have the following general formula:

    WHEREIN R is selected from the class consisting of H, aryl, alkyl, halo and arakyl having up to 10 carbon atoms, n is an integer from 1 to 18, Ar is an aromatic substituent, and M is selected from the class consisting of H, alkali metal, ammonium, and substituted ammonium. These compositions are useful in a wide variety of photochemical and photomechanical processes and are particularly suited for use as photopolymers, photoinitiators and photosensitizers in light sensitive coatings of presensitized lithographic plates.
