  • Patent number: 8343569
    Abstract: A laser markable security laser transfer film includes a carrier web formed from a laser light-transmissive material and a taggant-containing film disposed on the carrier web. The taggant-containing film is formulated from an energy sensitive taggant capable of withstanding temperatures of at least about 1800° F. to about 2200° F. The taggant absorbs energy at a first predetermined wavelength and, in response, emits energy at a second predetermined wavelength that is different from the first wavelength. The taggant-containing film further includes a polymeric resin. The taggant-containing film is disposed on the object to be marked with the taggant-containing film adjacent the object, and laser light is directed through the film to fuse the taggant-containing film onto the object to form a taggant-containing marking on the object.
