Abstract
A new direct thermal printable media includes an optically transmissive film that gives both form and protection to a layer of thermosensitive imaging material on a back surface of the film. Concentrations of heat applied to a front surface of the film form images within the thermosensitive layer that are visible through the film. A substrate is laminated to the thermosensitive layer on the back surface of the film for providing additional support independently of physical and chemical properties required for directly supporting thermosensitive imaging material.

A direct thermal printable laminate comprising:
- a thermally transmissive film having front and back surfaces;
- a thermosensitive imaging layer on said back surface of the thermally transmissive film;
- said thermosensitive imaging layer having a color developing mechanism reactive to transmissions of heat through said thermally transmissive film for forming images within said thermosensitive imaging layer;
- a substrate for supporting said thermally transmissive film also having front and back surfaces;
- and
- a bond between said back surface of the thermally transmissive film and the front surface of the substrate for laminating said thermally transmissive film to said substrate.
