ABSTRACT:
Photoimaging compositions comprising (A) a cyclohexadienone compound as defined, and at least one of (B.sub.1) a leuco dye or (B.sub.2) addition polymerizable ethylenically unsaturated monomer. A polymer binder can be present in the compositions. The new imaging compositions are useful in photoimaging products such as proofing papers, printout papers, overlay films and photopolymerizable elements useful for printing and photoresist purposes. The compositions have improved thermal stability.
