ABSTRACT:
An image-recording process is disclosed, which comprises using a photopolymerizable element comprising a polymerizable vinyl monomer and/or a polymerizable prepolymer, a photopolymerization initiator and a dye capable of being bleached with said vinyl monomer and/or prepolymer or a dye precursor capable of producing the bleachable dye upon being heated, conducting imagewise exposure to polymerize the photopolymerizable element, and heating it to bleach the dye with non-polymerized monomer and/or non-polymerized prepolymer remaining in portions not exposed or exposed or to bleach dye produced from the dye precursor upon heating. A negative working image-recording material for this process is also disclosed.
