Title: METALLIZED SCRATCH-OFF ON-DEMAND PRINTED CONSTRUCT
Abstract:
A direct thermal printable construct, such as a ticket, game piece, coupon, collection piece, label, security card, or voucher includes a thermally printable medium and a metallized layer bonded directly or indirectly to the thermally printable medium. A thermosensitive imaging layer of the thermally printable medium is printable by exposing the metallized layer to localized heat of a thermal printer for inducing local changes in the color of the thermosensitive imaging layer that are obscured from view through both the metallized layer and a base substrate of the thermally printable medium. One or more areas of the metallized layer are arranged to be removable by a scratching action using a fingernail or coin for revealing the underlying local changes in the color of the thermosensitive imaging layer.
