Antimicrobial coating for identification devices
First Claim
1. An identification device comprising:
- a face stock;
a protective coating positioned adjacent to at least a portion of at least one surface of the face stock; and
a water-based antimicrobial varnish layer receptive to a thermal transfer ink printing process and positioned adjacent at least a portion of the protective coating such that the protective coating is positioned between the face stock and the antimicrobial varnish layer, the antimicrobial varnish layer comprising an agent such that upon exposure of the device to moisture at least a portion of the agent is released to maintain an antimicrobial property of the antimicrobial varnish layer.

Abstract
An identification device that combines an antimicrobial coating with a printable substrate. For example, the invention includes a wristband with a face stock supporting indicia which are applied on (such as through thermal transfer printing) or through (such as through direct thermal printing) an antimicrobial layer. The antimicrobial layer is preferably a coating or varnish that is applied as the outermost layer and can bind with thermal transfer printing ink or supports pass through of direct thermal printing on a chemically receptive sublayer. The antimicrobial varnish includes varnish compounds and antimicrobial compounds such as a silver zeolite ion that is configured to react to moisture with a controlled release of microbial disinfectant. Preferably, the wristband is a hospital wristband bearing on-site printed identification indicia for a patient.

14. An identification device comprising:
-
a face stock; a thermal chemical imaging layer applied adjacent at least a portion of at least one surface of the face stock; a protective layer positioned adjacent at least a portion of the thermal chemical imaging layer such that the thermal chemical imaging layer is positioned between the face stock and the protective layer; and an ultraviolet curable antimicrobial layer positioned adjacent at least a portion of the protective layer such that the protective layer is positioned between the thermal chemical imaging layer and the antimicrobial layer, wherein the protective layer and the antimicrobial layer are configured to enable direct thermal printing onto the thermal chemical imaging layer through the antimicrobial layer and the protective layer. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
