Abstract
Abstract A thermal printing medium having high mechanical strength, and a label and tag incorporating such a thermal printing medium is disclosed. In additional to high mechanical strength, the thermal printing medium of the present invention provides for excellent printing density and reslution, for which reason the medium is very applicable to bar codes and the like. The thermal printing medium which includes a multilayer structure consisting of a support substrate comprised of polyolefin type cross-laminate film; a thermal developing layer over the above mentioned under layer, comprised chiefly of colorless or lightly colored leuco-type dye and color developer agent; and a protective layer over the above mentioned thermal developing layer.
