摘要： Compositions and systems for labeling substrates, such as optical disks, using leuco dye-containing coating compositions are described. The composition can comprise a color forming composition, an electromagnetic radiation absorber, and a stabilizing agent. The color forming composition can include a leuco dye, a hexaarylbiimidazole activator, and an acid-generating source. The absorber can be admixed with or in thermal contact with the color forming composition. The stabilizing agent can be configured for protecting the leuco dye upon exposure to ambient light, wherein the stabilizing agent comprises a diarylguanidine dye salt. The coating composition can be optimized for development using electromagnetic radiation having a frequency from about 760 nm and 800 nm.

摘要： 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 contain at least one polymeric binder, a specified leuco dye and a specified hydroxylamine compound. These compositions have the propensity for affording, upon thermal 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 can be imagewise heated to effect color formation (i.e., generation of an image) or, in case of compositions containing at least one near IR-absorbing dye, can be imagewise exposed to near IR radiation from a laser or other device to effect color formation (i.e., generation of an image).
摘要翻译：本文公开了新颖的可热成像的单色产品组合物，元件和方法。这些组合物和元件特征性地具有高对比度和快速成像速度。本发明的可热成像组合物含有至少一种聚合物粘合剂，特定的无色染料和特定的羟胺化合物。这些组合物具有在热成像时提供具有高光密度值的高度着色图像的倾向。同时，即使在广泛暴露于环境光之后，优选组合物的背景颜色也较低。这些组合物可以被成像加热以形成颜色（即，产生图像），或者在含有至少一种近红外吸收染料的组合物的情况下，可以成像地暴露于来自激光或其它装置的近红外辐射颜色形成（即图像的生成）。
