ABSTRACT:
The present invention concerns a phototackifiable composition useful as a coating on a substrate consisting of an optically clear blend of two or more polymers and a photosensitive compound that forms a strong acid on exposure to actinic radiation. The invention also relates to a process for coating such a composition on a support and toning the image-wise exposed composition on the support.
