Abstract: An identification device in the form of a wristband, labels, tags or cards, including a clear thermal sensitive coating laminated between a clear plastic coating and a liner ply having colored regions or printed matter. The colored regions or printed matter is visible through the clear thermal sensitive coating and clear plastic coating until the thermal sensitive coating is activated and becomes selectively opaque. The clear plastic coating having a uniform thickness allows for reliable thermal printing on the thermal sensitive coating with the clear plastic coating in place.

Abstract: A thermally activated, multi-color identification device having a substrate, an adhesive layer and a thermal activation layer underlying a protective coating. The thermal activation layer includes multiple regions of multi-colored thermal sensitive coating to achieve multi-color thermal printing on a single media. Alternatively, the thermal activation layer may be mono-color with regions of multi-colored ink underlying the thermal activation layer. The protective coating may be a polymer or varnish to protect the thermal activation layer from environmental hazards. The clear protective coating permits uniform activation of the thermal activation layer while protecting the same.

Abstract: An identification device in the form of a wristband, labels or cards, including a thermal sensitive coating laminated between a clear plastic coating and a liner ply. The clear plastic coating including UV inhibitors or anti-oxidants protects the thermal sensitive coating from damage by environmental hazards. The clear plastic coating also allows for reliable thermal printing on the thermal sensitive coating with the clear plastic coating in place.
