A roll of direct-thermal material may have a length of direct-thermal material including a facestock. An adhesive layer is on a first side of the facestock. A direct thermal coating is on a second side of the facestock, the direct thermal coating configured to selectively darken by heat activation when direct thermal printed. a cured ultraviolet LED coating is on the direct thermal coating, the cured ultraviolet LED coating having photoinitiators with substantial activation at an exposure limited to LED radiation at a 365 nm-450 nm wavelength range, and configured to allow direct thermal printing of the direct thermal coating therethrough, the cured ultraviolet LED coating curable without heat activating the direct thermal coating. The length of direct-thermal material being rolled on itself.

A visual security feature is provided that is disposed on a target. The visual security feature includes two substantially transparent layers. At least one of the two substantially transparent layers is present in an image-wise pattern.

Provided are a combination of a thermal transfer sheet and an intermediate transfer medium which is capable of accurately transferring only a transfer layer of the intermediate transfer medium desired to be transferred onto a transfer receiving article in the production of a print, and a thermal transfer sheet which is used in combination with an intermediate transfer medium. Also provided are a method for producing a print, comprising accurately transferring only a transfer layer of an intermediate transfer medium desired to be transferred onto a transfer receiving article, and a thermal transfer printer which is used in this method for producing a print. In the thermal transfer sheet which is used in combination with an intermediate transfer medium, inhibit layer 2 is disposed on substrate 1, and the inhibit layer 2 contains a carnauba wax.

Provided is a thermosensitive recording medium having excellent oil resistance among various performances required for the thermosensitive recording medium. The thermosensitive recording medium has a thermosensitive recording layer comprising a colorless or pale colored electron donating leuco dye and an electron accepting color developing agent on a substrate, wherein the thermosensitive recording layer contains N-[2-(3-phenylureido)phenyl] benzenesulfonamide and an urea-based compound represented by the general formula 1 as the electron accepting color developing agents,

A combined receipt and label roll comprises a core, and a web having a longitudinally-extending axis and wound on the core along the axis. The web includes (i) a substrate having a front side and a back side opposite the front side, (ii) a thermally-sensitive coating disposed on the front side of the substrate, and (iii) a water-based microsphere adhesive disposed on the back side of the substrate along the web axis. The water-based microsphere adhesive comprises at least four separate adhesive patches. The at least four adhesive patches are both sized relative to each other and positioned relative to each other on the back side of the substrate such that additional tack desired can be obtained by increasing volume of the adhesive patches without having to increase coat weight of the adhesive patches.

The thermal transfer image-receiving sheet according to the present disclosure includes a receiving layer, a front substrate, a porous layer, and a rear substrate in this order and further includes a metal-containing layer interposed between the receiving layer and the front substrate or between the front substrate and the porous layer. The thermal conductivity of the thermal transfer image-receiving sheet which is measured on the receiving layer-side is 0.38 W/m.Math.K or less. The Martens hardness of the thermal transfer image-receiving sheet which is measured on the receiving layer-side is 10.0 N/mm.sup.2 or less. The 45-degree specular gloss of the thermal transfer image-receiving sheet which is measured on the receiving layer-side is 800 or more.

A thermal adhesive paper including a base stock with a thermal ink layer covering at least a portion of the base stock top surface and an activatable adhesive layer covering at least a portion of the base stock bottom surface is described. The thermal adhesive layer can be used in a thermal printer for printing a transaction receipt, with the adhesive being selectively activated during printing. The activatable adhesive may be thermally activated, with a higher temperature needed to activate the adhesive than to activate the thermal ink.
