ABSTRACT:
Imaging materials employing photosensitive microcapsules having improved film speed are disclosed wherein the microcapsules contain a photoinitiator system including an absorber, a coinitiator and an autoxidizer; the absorber is a compound such as an aromatic ketone, the coinitiator and the autoxidizer are different but may be compounds such as N,N-dialkylanilines; the coinitiator and autoxidizer are selected such that free radical generation and oxygen consumption occur with optimum efficiency thereby providing an imaging material having high film speed.
