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。
