    • Provided are photoluminescent markings that contain a photoluminescent layer and one or more functional overlayers wherein the photoluminescent marking has an emission signature that lies partly or fully in the infrared region of the electromagnetic spectrum. One functional overlayer conceals the photoluminescent layer and blends into the background or blends with marks that are normally present, without significantly reducing the luminescent intensity of the photoluminescent layer. Another functional overlayer provides photolytic stability to the underlying photoluminescent layer. The invention also includes functional overlayers that enhance the daytime observability of the infrared emissions. A further functional overlayer prevents the observability of a printed message with the naked eye. A combination of functional overlayers each providing a different function is also included. As well, the present invention includes a multifunctional overlayer. The present invention also relates to methods of creating and using the inventive photoluminescent markings as well as objects containing the inventive photoluminescent markings.
    • 提供了含有光致发光层和一个或多个功能覆盖层的光致发光标记,其中光致发光标记具有部分或全部位于电磁光谱的红外区域中的发射特征。 一个功能性覆盖层隐藏光致发光层并且与通常存在的标记共混成背景或掺合物,而不显着降低光致发光层的发光强度。 另一功能性覆盖层为底层光致发光层提供光解稳定性。 本发明还包括增强红外发射的白天可观察性的功能覆盖层。 另外的功能覆盖层用肉眼防止印刷信息的可观察性。 还包括功能覆盖层的组合,每个功能覆盖层提供不同的功能。 同样,本发明包括多功能覆盖层。 本发明还涉及产生和使用本发明的光致发光标记的方法以及包含本发明的光致发光标记的物体。
