A thermally imageable element having a thermally imageable layer, wherein the thermally imageable layer has a thermal amplification additive and a stabilizer selected from the group consisting of phenolic type compounds and amine type compounds. These stabilizers present in thermally imageable layers maintain NIR stability during manufacture, and when the thermally imageable elements containing them are used in thermal imaging processes.

Thermal imaging elements having improved stability

A process for adjusting the energy of an imaging laser for imaging of a thermally imageable element including the steps of: (a) providing an imaging unit having a non-imaging laser and an imaging laser, the non-imaging laser having a light detector which is in communication with the imaging laser, (b) contacting a receiver element with the thermally imageable element in the imaging unit, wherein the receiver element comprises a light attenuating layer having a front surface and a back surface; (c) actuating the non-imaging laser to expose the thermally imageable element and the receiver element to an amount of light energy sufficient for the light detector to detect the amount of light reflected from the thermally imageable element and light attenuating layer of the receiver element; and (d) actuating the imaging laser to focus the imaging laser in order to expose the thermally imageable element to an amount of light energy sufficient for imaging the thermally imageable element.

Receiver element for adjusting the focus of an imaging laser

A receiver element for use in a thermal imaging process, wherein a surface of a pigment-image receiving layer of the receiver element has a roughness, and the surface is brought into contact with a thermally imageable element, wherein the pigment-image receiving layer provided on the receiver element has an average roughness (Ra) of less than about 1&mgr; and has surface irregularities having a plurality of peaks, at least about 50 of the peaks having a height of at least about 200 nm and a diameter of about 100 pixels over a surface area of about 458&mgr; by about 602&mgr;. These roughened receiver elements substantially reduce the micro-dropouts.

Receivers and their use in thermal imaging

Storage-stable photoimageable leuco dye/photooxidant compositions and imaging processes utilizing these compositions are disclosed. These compositions comprise deuterated leuco compounds, e.g., deuterated aminotriarylmethanes, wherein the extent of deuteration is preferably at least 60%. These new compositions and the processes utilizing these new compositions afford improved monochrome images having enhanced film stabilities and image contrast characteristics, wherein desirable higher optical densities in imaged areas (D.sub.imaged) and desirable lower optical densities in unimaged areas (D.sub.unimaged, D.sub.fixed, and D.sub.forccd) are simultaneously both achieved in accordance with the compositions and processes of the instant invention.

Storage-stable photoimageable deutero leuco dye/photooxidation

A photosensitive element adapted for the preparation of colored images is disclosed. The photosensitive element comprises: a photosolubilizable layer consisting essentially of an acid-labile polymer and a photosolubilizing agent; an elastomeric layer; and a support. It can be processed by aqueous solvents, preferably ordinary tap water.
