  • Patent number: 6524000
    Abstract: Recording materials are converted in a direct thermal imaging apparatus to time temperature indicators by exposure to heat from the thermal print head of a direct thermal printer. Methods for converting a recording material to a time temperature indicator comprise heating the recording material with a direct thermal imaging apparatus. The recording material contains an indicator compound which is convertible from an inactive state to an active state when heat is applied thereto by a direct thermal imaging apparatus for less than one second. Time-temperature indicators with active indicator compounds in a printed pattern are formed by a direct thermal imaging apparatus.

  • Patent number: 5992314
    Abstract: A thermal stencil master sheet for stencil printing has a porous substrate for absorbing ink and a thermoplastic resin film bound thereto by an adhesive. The stencil pattern is formed in both the film and adhesive. The adhesive comprises a thermoplastic resin derived from UV and visible light cured monomers, oligomers and mixtures thereof. In the method provided, thermal stencil master sheets are prepared by forming a liquid layer of adhesive between the porous substrate and the thermoplastic resin film and curing the liquid layer by exposure to UV or visible light.

  • Patent number: 5952098
    Abstract: There is provided by the present invention a thermal transfer ribbon which employs reactive binder components that increase in molecular weight when heated during transfer to provide images with high scratch and smear resistance. The reactive components comprise an epoxy resin binder and crosslinker for the epoxy resin binder which are maintained in separate phases within the thermal transfer layer until exposed to a thermal print head through the use of a coating formulation solvent which does not solubilize either the crosslinker or the epoxy resin binder or both.

  • Patent number: 5883043
    Abstract: A thermal paper with an image derived from a water-based security ink has more than one means of security. A variable light absorbing and/or transmitting pigment or dye in the ink is a first security and a water repelling agent in the ink is a second security. A pseudo-watermark from the coloration of the ink under ambient conditions is a third security. Visible images can be generated from the printed ink upon exposure to UV or infrared light. Methods of preparing the thermal paper comprise printing the security ink on thermal paper with only one thermosensitive coating on the surface opposite the thermosensitive coating.

  • Patent number: 5866643
    Abstract: There is provided by the present invention methods for preparing coating formulations and thermal transfer ribbons which provide images of high resolution by thermal transfer printing. The formulations contain an incompatible resin or wax component for reduced cohesiveness between the components of the thermal transfer layer. These methods employ thermoplastic resins and waxes with distinct solubility in the absence of solvent to reduce cohesion but are sufficiently compatible as to exhibit film forming properties. A method for modifying a coating formulation is also provided where an incompatible resin or wax components is added thereto.

  • Patent number: 5824399
    Abstract: A thermal transfer medium is provided which is sufficiently opaque to be sensed by optical sensing means, yet forms images which can be transparent or semi-transparent (or opaque). The thermal transfer medium comprises a transparent substrate and multi-layer structure of a thin first coat and a thick second coating. The coatings are formulated such that only the second coating transfers to a receiving substrate upon exposure to a print head of a thermal printer leaving the first coat positioned on the transparent substrate. Separation of the two coatings allows the transparency/opacity of the image to be independent of the transparency/opacity of the first coats and the thermal transfer medium.

  • Patent number: 5744226
    Abstract: A thermal transfer medium which forms images having a matte finish is provided which comprises a substrate, a thin first coating and a thick second coating. The coatings are formulated such that only the second coating transfers to a receiving substrate upon exposure to a thermal print head leaving the first coating positioned on the substrate. Separation of the two coatings provides images with a matte finish. The first coating has a higher softening point than the second coating and in preferred embodiments, the binder resin in the first coating provides higher adhesion to the substrate than the binder resin in the second coating.

  • Patent number: 5741592
    Abstract: A coating formulation which forms a heat sensitive coating and a thermal recording material with such a coating are disclosed. The heat sensitive coating shows improved prerecording shelf life and improved record stability and consists of microcapsules containing a solid blend of dye and sensitizer, with the exterior of the capsules consisting of color developer and other coating materials such as pigment, binder and additives. Application of heat during printing renders the microcapsule walls permeable to the dye resulting in color development upon reaction of the dye and color developer.
