  • Publication number: 20150119238
    Abstract: A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; colouring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for colouring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the coloured surface. The colouring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.

  • Patent number: 7384890
    Abstract: A security feature and method for verifying the authenticity of commercial paper. In one embodiment, pearlescent ink is added to a portion of commercial paper stock. A recipient can then tilt the commercial paper stock to view the pearlescent ink mark, design, or spot from different angles, causing the pearlescent ink to appear different colors and verifying the authenticity of the commercial paper. Further, according to another embodiment, thermochromic ink is applied to a portion of commercial paper stock. A recipient can then apply heat to the commercial paper stock in the area of the ink mark, thereby causing the thermochromic ink to disappear or change colors.

  • Patent number: 7235512
    Abstract: The present invention provides a heat-sensitive recording material comprising a substrate; and at least two heat-sensitive recording layers provided on the substrate, the heat-sensitive recording layers including microcapsules encapsulating an electron-donating dye precursor, and an electron-accepting compound, which reacts with the electron-donating dye precursor to develop a color and is disposed outside of the microcapsules, wherein the microcapsules include at least two kinds of microcapsules having different glass transition temperatures. A difference between each of the glass transition temperatures of the at least two microcapsules having different glass transition temperatures is preferably in a range from 20° C. to 70° C. According to the invention, a heat-sensitive recording material, which is superior in the reproduction of the gradation of an image and enables recording at high density, is obtained.

  • Patent number: 7176161
    Abstract: There are disclosed imaging members wherein a chemical compound in a crystalline form is converted, at least partially, and preferably substantially completely or completely, to a liquid in the amorphous form, the liquid having intrinsically a different color from the crystalline form. Also described are imaging methods utilizing the imaging members. The conversion of the compound from the crystalline form to the liquid form can be effected by the application of thermal energy or by other imaging techniques.

  • Patent number: 7166558
    Abstract: A multicolor imaging system is described wherein at least two, and preferably three, different image-forming layers of a thermal imaging member are addressed at least partially independently by a thermal printhead or printheads from the same surface of the imaging member by controlling the temperature of the thermal printhead(s) and the time thermal energy is applied to the image-forming layers. Each color of the thermal imaging member can be printed alone or in selectable proportion to the other color(s). Novel thermal imaging members are also described.

  • Patent number: 7001868
    Abstract: To provide an image recording method and apparatus that can record and display an image of free pattern without forming the complex wirings in an electrochromic material, and to reduce the manufacturing costs of the image recording apparatus employing the EC material. A recording sheet 7 having a coloring layer made of an electrochromic material and an electrolytic layer with an increasing electrical conductivity in a specific temperature range is employed, and a recording head 13 with a plurality of heating elements arranged in a linear direction is moved relative to the surface of the recording sheet 7 in the direction orthogonal to the linear direction while at the same time a voltage is applied to the front and back faces of the recording sheet 7, thereby selectively heating the heating elements 11. Thereby, a coloring reaction is caused only in a part where heat is applied by the heating elements of the recording sheet 7 and voltage is applied to form an image on the recording sheet 7.

  • Patent number: 6916765
    Abstract: The invention relates to consumer product packages having impact promotional items printed directly on the package and methods for manufacturing such product packages. An image constituting the impact promotional item is printed using blended printing inks and sublimation dyes onto a paperboard blank, which is folded to form a product package. The printed image has a visual appearance substantially unchanged from a conventional printed image. The sublimation dyes present in the printed image supply a transferrable image component that, following transfer to a substrate such as a fabric article, accurately reproduces the printed image viewed by the consumer on the product package. Printing ink and sublimation dye blends for printing the image are also disclosed, as are methods for transferring the transferrable image component to an article, such as a fabric article or textile.
