  • Patent number: 7588656
    Abstract: The present invention pertains to a donor element comprising a support layer, a transfer layer supported by the support layer, and a second layer disposed between the support layer and the transfer layer, wherein the second layer contains a binder and optionally an uncured crosslinking agent, but substantially no pigment. The binder in the second layer has a molecular weight Mn that causes the second layer to be substantially transferred with the transfer layer when the donor element is exposed to light.

  • Patent number: 5955224
    Abstract: Novel thermally imageable monochrome product compositions, elements, and processes are disclosed herein. These compositions and elements characteristically have high contrast and fast imaging speeds. The thermally imageable compositions of this invention comprise (a) at least one near IR-absorbing dye having the structure given in the specification; (b) at least one HABI compound; (c) at least one leuco dye; (d) at least one acid-generating compound; and (e) a polymeric binder. Optionally at least one UV stabilizer and/or at least one inhibitor of color formation can also be present. These compositions have the propensity for affording, upon imaging, highly colored images having high optical density values. At the same time, background color is low in preferred compositions even after extensive exposure to ambient light. These compositions are imagewise exposed to near IR radiation from a laser or other device to effect color formation (i.e., generation of an image).
