ABSTRACT:
The photosensitive composition of this invention contains (1) an ethylenically unsaturated component capable of forming a high polymer by addition polymerization or crosslinking, (2) a cyclic cisoid conjugated diene as a photooxidizable component capable of reacting with singlet oxygen to form an endoperoxide, and (3) a photooxygenation sensitizer. A process for preparing a photosensitive element, such as a relief printing plate, embodying a layer of such a composition is described.
