  • Patent number: 8883380
    Abstract: On a film where an exposure material coating has been formed in a exposure pattern formation region on a film base material, a colored firing material, colored light-curable material, or colored ink is applied to at least one of two widthwise side edges to form a side part application coating, which is irradiated with laser light by an alignment mark formation unit to form an alignment mark. The alignment mark is then used to detect film meandering and adjust the positions of masks. This makes it easy to form the alignment mark and detect the alignment mark thus formed and makes it possible to accurately correct for meandering of a film and stably expose the film in the process of continuous exposure of a film where an exposure material coating has been formed in a exposure pattern formation region on a film base material.

    Abstract: A multilayer sheeting with a 3D floating image. The sheeting includes a layer of microlenses and a multilayer material disposed adjacent the microlenses. The multilayer material includes multiple adjacent layers having X-Y planar positions and a Z-direction orthogonal to the X-Y planar positions. Individual images, which contrast with the material, are formed in the multilayer material and include connected elements at interfaces between the multiple layers and conjunction elements between connected elements. The connected elements are registered in the Z-direction at the X-Y planar positions in the interfaces between the layers. The individual images collectively form a composite 3D image that appears to the unaided eye to be three-dimensional and floating above or below the sheeting, or both.

Upon selective exposure of certain regions of the matrix by radiation, most normally laser light radiation, the dye will initially migrate and redistribute itself to radiatively-exposed regions until, dye migration being substantially complete, photopolymerization will occur, locking the migrated dye in place at a relatively higher concentration at the selectively exposed regions. The dye therein stably located can be optically detected by, preferably, light-radiation-stimulated fluorescence.

  • Patent number: 7052812
    Abstract: A host matrix—normally a binder such as cellulose acetate propionate in a solvent such as acetone—contains a radiation-polymerizable photopolymer—normally a monomer like dipentaerythritol pentaacrylate in combination with a crosslinker like 1-vinyl-2-pyrrolidinone, an initiator like N-phenyl glycine, and/or a photosensitizer like camphor quinone—that is initially uniformly doped with a stable dye—typically Rhodamine B and/or Bodipy Red—that photoinitiates photopolymerization. Upon selective exposure of certain regions of the matrix by radiation, most normally laser light radiation, the dye will initially migrate and redistribute itself to radiatively-exposed regions until, dye migration being substantially complete, photopolymerization will occur, locking the migrated dye in place at a relatively higher concentration at the selectively exposed regions. The dye therein stably located can be optically detected by, preferably, light-radiation-stimulated fluorescence.

  • Patent number: 6908728
    Abstract: By irradiating a laser beam onto an X-ray film that includes a support layer having disposed thereon an emulsion layer, the emulsion layer is melted, numerous minute air bubbles are generated in the emulsion layer, and the emulsion layer becomes convex, whereby a visible dot pattern is formed. The irradiation time and wavelength of the laser beam are selected so that separation is not generated between the support layer and the emulsion layer. By defocusing and irradiating the laser beam, the X-ray film may substantially uniformly receives energy of the laser beam. Moreover, an undersurface layer may also be formed, and the laser beam may be irradiated onto the undersurface layer to form a dot pattern on the undersurface layer. A device and a method for forming a marking pattern representing identification information on a rolled photosensitive material and cutting the photosensitive material into sheets are disclosed.

  • Patent number: 6864039
    Abstract: A photosensitive printing element comprising a support; and a photopolymerizable layer comprising a photopolymerizable composition comprising at least one elastomeric binder, at least one monomer, an initiator having sensitivity to actinic radiation, and at least one photobleachable compound having sensitivity to actinic radiation; is described. Preferred photobleachable compounds are unsubstituted or substituted naphthylvinyl pyridines; unsubstituted or substituted styrylquinolines; diphenyl maleic anhydride; isomers of any of the foregoing; derivatives of any of the foregoing; and any combination of the foregoing. Such photosensitive printing elements are used to prepare flexographic printing plates and are useful in enhancing resolution and differentiating image areas from non-image areas in images produced therefrom by reducing the deleterious effect of scattered light.

  • Patent number: 6815147
    Abstract: The laser beam ablatable film of the invention includes an ablatable metallic layer arranged below a translucent protective layer that is dyed through-out. The metallic layer is connected to a contrastive colored layer by a transparent connecting layer, and the contrastive colored layer is connected to a plastic film. The entire assemblage of laminated layers can also include a self-adhesive film applied to the plastic film and the self-adhesive layer is then covered by a removable carrier material. This laminated assembly can be stamped into individual labels that can be detached from the carrier material and placed onto objects. When the ablatable foil of the invention is subjected to a laser beam surface areas of the laminated assembly appear as a mixture of colors of letters or symbols resulting from the color filter effect of the protective film.

  • Patent number: 6767676
    Abstract: The optical functional element contains aggregates of developed silver grains obtained by developing silver halide grains arranged so as to constitute a periodical structure. The element includes a substrate and a medium layer. The aggregates of the developed silver grains are arranged in the medium layer so as to constitute said periodical structure. The element is produced by first selectively exposing a photo-curing resin layer formed on said substrate in which the silver halide grains are dispersed so as to selectively photo-cure the photo-curing resin layer, then overall exposing the photo-curing resin layer to expose the silver halide grains in the photo-curing resin layer, and thereafter developing the photo-curing resin layer.
