Abstract

A sealed self-contained photohardenable imaging assembly comprising: PA1 a first transparent polymeric film support; PA1 a second polymeric film support which may be opaque or transparent; PA1 an imaging layer disposed between said first transparent support and said second support; PA1 a subbing layer disposed between said first transparent support and said imaging layer, said subbing including a polymer having chemical moieties which bond to said microcapsules; and an adhesive material disposed between said imaging layer and said second support; PA1 said imaging layer comprising a developer material and a plurality of microcapsules, said microcapsules encapsulating a photohardenable composition containing a color precursor, a polyethylenically unsaturated compound, a cyanine dye/borate photoinitiator and a disulfide having the formula: ##STR1## where X is selected from the group consisting of S and O except X is N when the disulfide includes one or more tetrazolyl groups; n represents 0 or 1; A represents the residue of the ring containing the N, C and X atoms, the ring containing five or six members and, in addition, said ring members may be fused to an aromatic ring; and R.sup.5…
