    • A thermally imageable element can be imaged using heat alone without the need for photosensitivity or post-imaging processing. The element contains image-forming chemistry that comprises i) image precursor chemistry and ii) a catalyst or a catalyst precursor that upon imagewise heating is capable of promoting thermally induced image formation with the image precursor chemistry. The image-forming chemistry i) and ii) components are in reactive association and uniformly dispersed or dissolved within a binder in one or more layers of the element. Thus, the element is capable of being thermally addressed to provide a visible image as a result of thermally induced catalytic transformation of the image-forming chemistry.
    • 可热成像元件可以使用加热单独成像,而不需要光敏性或后成像处理。 该元件包含图像形成化学,其包括i)图像前体化学和ii)在图像加热时能够促进图像前体化学物质的热诱导图像形成的催化剂或催化剂前体。 图像形成化学i)和ii)组分是反应性缔合的,并且均匀分散或溶解在该元素的一个或多个层中的粘合剂中。 因此,作为图像形成化学品的热诱导催化转化的结果,该元件能够被热寻址以提供可视图像。
