Abstract
The present invention relates to chromogenic material that may respond and shift in color due to environmental conditions such as heat, light or humidity. The light may include both visible and non-visible light, such as ultraviolet light. The chromogenic material may therefore provide a method to independently develop a latent image on a given substrate, and in particular, to a substrate that includes conventional thermosensitive image forming media.
