Abstract
Self-expiring labels and badges are made by a method of: (A) contacting a first component of a dye system with a second component of the dye system, the first component carried on a facial surface of a transfer ribbon and the second component carried on a facial surface of a media, the second component beneath and in contact with a timing layer, and (B) heating the contacted first component of the dye system and timing layer with a thermal print head such that (i) the first component of the dye system transfers to the timing layer, and (ii) the first component of the dye system begins to migrate through the timing layer to the second component of the dye system which, upon contact of the first and second components of the dye system, an image is formed.
