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.
