Antimicrobial coating for identification devices

摘要

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.

主权项

1. An identification device comprising:
a face stock; a protective coating positioned at least one of proximate or adjacent to at least a portion of at least one surface of said face stock, wherein the protective layer consists of resin and a plurality of fillers and binders; and a water-based antimicrobial varnish layer receptive to a thermal transfer ink printing process and positioned on at least a portion of said protective coating, said antimicrobial layer comprising a silver zeolite containing silver ions such that upon exposure of the device to moisture at least a portion of the silver ions are released to maintain an antimicrobial property of the antimicrobial layer.
