The present invention provides a means to produce an image in gray scale
on a film using direct thermal imaging, and preferably near infrared
direct thermal imaging. The present invention provides a multi-layered,
laminated, non-cavitated film that has proper surface characteristics and
heat transfer properties by virtue of the proper combination of polymeric
layers and coatings, in particular, the active direct thermal coating,
and topcoat which produce direct thermal imaging with gray scale. Such a
film may be used for temporary personal identification devices, for
instance, hospital wristbands and backstage passes, and may incorporate
bar code data, photographs as well as other pertinent data.
