    摘要： A laser-imageable direct write medium comprising an infrared dye in photoreactive association with a leuco dye, in which irradiation of the medium at a wavelength absorbed by said infrared dye converts said leuco dye to the corresponding dye, characterised in that the said infrared dye comprises a chromophore which is formally the product of a one-electron or two-electron oxidation of a p-phenylenediamine or a 4,4'-biphenylenediamine.

    摘要： A photothermographic element comprising a support bearing an image forming system comprising:
    (a) a photosensitive silver halide (b) an organic silver compound (c) a polymer binder and (d) a reducing agent for the organic silver compound, characterised in that the reducing agent comprises a redox-dye-releasing compound of the general formula:
    in which:
    R represents an organic group which may be oxidatively cleaved to a thermally immobile form, A represents a bond or a divalent linking group having a chain consisting of up to 12 atoms, which is linked to the carbonyl group via a carbon atom or an oxygen atom, and D represents the chromophore of a thermally mobile dye.
