摘要:
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.

摘要:
A photoluminescent marking that includes a photoluminescent layer and at least one functional overlayer is disclosed. The photoluminescent layer comprises at least one type of photoluminescent material. The at least one functional overlayer is adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking or to prevent the observability with the naked eye of a printed message on the marking. Also methods of making and using the inventive photoluminescent marking are disclosed.
