  • Patent number: 6740465
    Abstract: Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images.

  • Publication number: 20030124451
    Abstract: A method and apparatus for producing identification (ID) cards using a photosensitive imaging system employing microcapsules is described. In accordance with one aspect of the invention, ID cards are produced by translating an image containing identifying indicia into a latent image on an appropriate photosensitive donor sheet, pressure developing the latent image, forming a full color print of the image on a developer sheet, laminating an ID card substrate in registration with the image to the developer sheet and die cutting the laminated article to produce an ID card. Self-contained imaging systems can also be used to produce identification cards. The image preferably includes unique information useful in identifying the card holder such as a photograph, fingerprint, signature, description, name, etc. The identifying indicia may be combined with non-variable information including background printing, card issuer data, logos, security features, etc.

  • Patent number: 4842981
    Abstract: An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a layer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.

  • Patent number: 4822714
    Abstract: A transfer imaging system is disclosed wherein images are formed by image-wise exposing a layer comprising a chromogenic material and pressure rupturable capsules containing, as an internal phase, a photosensitive composition. In a preferred embodiment, the chromogenic material is encapsulated with the photosensitive composition. Upon exposure and capsule rupture the chromogenic material is image-wise transferrable to a developer or copy sheet where the chromogenic material reacts with a developer to form an image. Preferred systems are sensitive to U.V. or blue light in the wavelength range of 380 to 480 nm.

  • Patent number: 4816367
    Abstract: A multicolor imaging material comprises a substrate, a capsule layer made up of a plurality of heat-meltable microcapsules including color former and a developer material layer. When the laser beams having wavelengths of .lambda..sub.1, .lambda..sub.2, and .lambda..sub.3 are applied to the multicolor imaging material according to the signals corresponding to three primary colors, the heat-meltable microcapsules for individual colors independently generate heat, thereby causing the heat-meltable substance to be melted. This brings about the reaction of the color formers for individual colors with the developer to developer colors, thereby forming a color image comprised of cyan, magenta and yellow.

  • Patent number: 4810603
    Abstract: The tonality of a produced color image transferred to an image receiving material is measured. The differences between equivalent neutral shades of a reference color image and equivalent neutral shades of the reproduced color image are compared to calculate tonal correction values for corrected equivalent neutral shades. Tonality correction means is controlled on the basis of said tonal correction values.

  • Patent number: 4777108
    Abstract: The present invention provides a transfer imaging sheet wherein an image is invisible in visible light but apparent under ultraviolet or infrared radiation. The transfer imaging sheet comprises an imaging sheet having a coating on one surface thereof of an image forming agent selected from the group consisting of an ultraviolet-readable fluorescer and an infrared-readable dye, and a radiation curable composition which undergoes an increase in viscosity upon exposure to actinic radiation. The radiation curable composition is encapsulated in rupturable microcapsules as an internal phase, and preferably, the image forming agent is encapsulated with the radiation curable composition.
