Abstract
A thermal sensitive label, and method of manufacture, provide a label construction which is resistant to abrasion without requiring additional coatings. A substantially transparent synthetic material substrate (typically about 1-3 mils thick, but no more than 5 mils thick) has a thermally sensitive coating applied to a first face so that when heat is applied to the second face an image will form on the thermally sensitive material and it will be readable from the second face without significant distortion. A pressure sensitive adhesive, which is preferably pigmented, is disposed on the thermally sensitive material, and may be covered with a release liner. Alternatively, an adhesive release material may be applied on the second face of the substrate.
