Abstract

Photopolymerizable elements comprising a support, a layer of a photopolymerizable composition and a protective layer, the photopolymerizable layer having in reactive association therewith, e.g., dispersed therein or in contact with the surface, pressure rupturable microcapsules containing therein at least one active component for the photopolymerizable composition, e.g., ethylenically unsaturated compound, sensitizer, photoinitiator, oxygen scavenger, and plasticizer. Processes for the preparation of an activated photopolymerizable element and use are described wherein the microcapsules are ruptured, i.e., prior to imagewise exposure and development. The photopolymerizable elements are useful as color proofs, printing plates, etc.
