Abstract: A thermal indicator using indicia formed by opaque ink applied to a thermal imaging material element is described. The ink is substantially the same color as the imaging element background and remains substantially hidden until the imaging element background changes color when heated. Time-temperature exposure indicating labels can be prepared using a printer with direct thermal type and ink jet type print heads.

Abstract: A process of making an image element having an imperceptible message that becomes readily apparent when the image element is exposed to an excessive amount of heat and/or UV radiation is provided. The process comprises providing a first thermally sensitive coating on at least a first portion of the image element; pre-printing a first mark on the first portion of the image element, wherein the first pre-printed mark comprises non-thermally sensitive ink. The image element may be associated with a material such that, upon becoming readily apparent, the imperceptible message provides a warning that the material has been exposed to excessive heat and/or UV radiation.

Abstract: A thermal paper with a fluorescent security mark printed on the thermosensitive coating that is responsive to wavelengths in the range of 200 nanometers to 400 nanometers. The mark is either printed on the thermosensitive coating directly or on an optional protective top coat positioned over the thermosensitive coating. Methods of preparing the thermal paper comprise printing a solution, dispersion or emulsion of a fluorescent compound on the thermal paper by flexographic printing.

Abstract: Thermosensitive recording materials such as thermal paper have printed indicia of high quality on the back thereof printed on a backcoating. This backcoating also incorporates an optically variable compound which provides a security feature.

Abstract: A duplex envelope includes a face sheet divided into a top page, bottom page, inner flap, and outer flap. A complementary liner is divided into a pocket bonded to the bottom page to define an inner envelope, an inner tab removably bonded to the inner flap, and an outer tab removably bonded to the outer flap. The top page is foldable over the liner pocket for defining an outer envelope closed by the outer flap.

Abstract: Thermosensitive recording materials such as thermal paper with a thermochromic composition applied to the back thereof and overcoated with a protective coating provide a security feature without pre-reacting the active compounds in the thermosensitive recording materials or causing the loss of the color-forming properties of the thermosensitive recording materials. Methods for preparing thermal papers with a thermochromic composition as a security feature apply a thermochromic printing ink to the opposite side of the thermosensitive layer of the thermal paper followed by a coating composition that forms a protective coating over the thermochromic ink. The thermochromic printing ink and coating composition are selected so as not to pre-react with the thermosensitive layer or cause the loss of the color-forming properties of the thermosensitive layer.

Abstract: A business mailer includes a face sheet having a strip of adhesive bonded to one side thereof along a corresponding edge. A liner is bonded to the face sheet atop the adhesive strip, and is severed around a central strip tab for being removed from a surrounding border of the liner for exposing the adhesive strip. This integrated construction may be printed at high speed following which the liner tab is removed and the face sheet folded to form an adhesively sealed business mailer.

Abstract: A thermal paper with an image derived from a U.V., visible light or electron beam curable security ink has more than one means of security. Water repelling properties of the ink are a first security. A variable light absorbing and/or transmitting pigment or dye in the ink, pseudo-water mark or both, provide one or more additional security measures. Methods of preparing the thermal paper comprise printing the security ink on thermal paper on the surface opposite the thermosensitive coating and exposing the print to a U.V., visible light or electron beam radiation.
