  公开（公告）日：2004-09-23

  Photothermographic elements employing improved base precursors that undergo thermal decomposition are disclosed. Thermal-dye-bleach agents, and in particular, a novel class of salts of arylsulfonylacetic acids as bleaching agents for photothermographic use are disclosed. Photothermographic elements employing these thermal-dye-bleach agents are suitable for use as acutance and antihalation systems, bleachable filter dye materials, and in promoting unblocking of various components such as blocked developers, especially in photothermographic elements.

• A method of forming an image, and an imaging element for inhibiting image formation with cobalt (III) complexes

  An imaging element contains an energy-activatable image precursor composition comprising a cobalt III complex having releasable ligands which react with an image forming material to form a visible image. The element also contains a photoinhibitor which, on activating exposure, inhibits the release of ligands from the cobalt III complex or inhibits their image forming action. Images may be formed by imagewise activating the photoinhibitor, preferably with radiation longer than 300 nm, and thereafter activating the image precursor composition, for instance by heating. Images of a different sense may be formed by varying the exposure and activation treatments of the element.

  一种成像元件包含一种能量可激活的成像前体组合物，该组合物由钴 III 复合物组成，该钴 III 复合物具有可释放的配体，这些配体与成像材料反应形成可见图像。 该元件还包含一种光抑制剂，该光抑制剂在激活曝光时可抑制配体从钴 III 复合物中释放或抑制其成像作用。 可以通过成像激活光抑制剂（最好使用长于 300 纳米的辐射），然后激活成像前体组合物（例如通过加热）来形成图像。 可以通过改变元件的曝光和激活处理来形成不同意义的图像。

  Improved photothermographic elements are spectrally sensitized with a combination of cyanine dyes that provides efficient sensitization together with excellent keeping stability and low dye stain. The photothermographic elements comprise a photosensitive silver halide, an organic silver salt, such as silver behenate, and a reducing agent. The dye combination utilized as a spectral sensitizer for the silver halide is a combination of a first cyanine dye containing two thiazole nuclei and a second cyanine dye containing a thiazole nucleus and an oxazole nucleus.
