  • Patent number: 9250527
    Abstract: An imageable material can be used to form a mask image for providing a relief image. This imageable material has a simplified structure and consists essentially of, in order: a transparent polymeric carrier sheet and a barrier layer comprising a first infrared radiation absorbing compound. A first ultraviolet radiation absorbing compound is provided in the transparent polymeric carrier sheet or the barrier layer. A non-silver halide thermally sensitive imageable layer is disposed on the barrier layer and comprises a second infrared radiation absorbing compound and a second ultraviolet radiation absorbing compound. A relief image is formed by imaging the imageable material to form an imaged mask material, exposing a relief-forming material with curing radiation through the imaged mask material to form exposed regions and non-exposed regions, and developing the imaged relief-forming material to form a relief image by removing its non-exposed regions.

  • Patent number: 8824828
    Abstract: A method of fusing two images includes adjusting contrast of (a) a visual image and (b) a thermal image. Also included is modifying the adjusted contrast of the thermal image to form output brightness levels, by using a transformation curve, and then displaying both (a) the brightness levels of the thermal image and (b) the adjusted contrast of the visual image. Modifying the adjusted contrast of the thermal image includes using a V-curve as the transformation curve, in which the V-curve includes similar maximum output brightness levels at the coldest and hottest relative temperatures, respectively. The V-curve also includes a minimum output brightness level at a midpoint between the coldest and hottest relative temperatures. Furthermore, the method assigns different hues to the intensity values of the thermal image, ranging from coldest to hottest relative temperatures.

The medium incorporates one or more types of microstructures having a predetermined heat or radiation modifiable optical characteristic such as color, scattering, diffusion, diffraction, interference and iridescence. Associated intimately with the microstructures is a radiation antenna that acts to absorb radiation from a radiation source. The radiation antenna and source are attuned to one another to efficiently transfer energy therebetween and subsequently to the microstructures; this transfer of energy results in the modification of an optical characteristic of the microstructures to form an image on the medium. The medium has one or more layers that may include both the radiation antenna and the microstructures. Alternatively, the microstructures and radiation antenna may be included in separate layers. Coatings that incorporate one or more layers that include distinct microstructures and radiation antennae are also contemplated.

  • Patent number: 7094517
    Abstract: High sensitive organic dye-in-polymer (DIP) medium for write-once-read-many (WORM) optical discs with fluorescent reading. The medium consists of a fluorescent color means, capable of absorbing writing radiation produced by a laser, a compound capable of generating free radicals upon influence of heat produced by the writing radiation and a polymer capable of producing a translucent film enabling high quantum yield of the fluorescence induced in the color means. The color means can be selected from xanthene dyes of the eosine and rhodamine groups, acridine, oxazine, azine, peylene, violanthrone, cyanine, phtalocyanine, indigoide colors and porphyries. The free radicals generating compound can be chosen from the group of compounds comprising azo and diazoi compounds or peroxyde compounds. The film producing polymer can be selected from the group of compounds comprising cellulose ethers, vinyl resins or acrylic resins.

  • Patent number: 7049054
    Abstract: Thermally developable imaging materials have an outermost protective layer that is composed of one or more hydrophilic film-forming components. Between the outermost protective layer and the underlying thermally developable imaging layers is an interlayer containing a film-forming ionic latex polymer other than a carboxy-containing latex polymer. This ionic polymer can be negatively-charged or positively-charged. The ionic latex polymer is present as latex particles that have been prepared in the presence of a stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.

  • 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: 6692895
    Abstract: A laser imageable article includes an imageable layer that comprises the reaction product of a metal precursor and a reactant. The imageable article also includes a first boundary layer on a first side of the imageable layer, the first boundary layer being substantially transparent to laser radiation, and a second boundary layer on a second side of the imageable layer. The imageable layer may be imaged with a laser through the first boundary layer while maintaining the continuity of the first boundary layer. In a preferred embodiment, the imageable layer comprises the reaction product of an ion of one or more metals selected from columns 8, 9, and 10 of the periodic table of elements and a reducing agent selected from hypophosphorus acid and salts thereof, sodium borohydride, and dimethylamine borane. One preferred embodiment of the imageable layer comprises from 1 to 30 mole percent phosphorus and up to 99 mole percent nickel.

  • Patent number: 6689542
    Abstract: A process for marking which enables a colored pattern formed by at least two different and contrasting colors to be created on a dark or black surface of a rubber article, which process includes preparing a light-colored rubber composition having at least one elastomer and at least two coloring agents of different light colors, giving the said composition its initial color, and then incorporating a dark or black masking agent into this colored composition in a limited proportion to darken or mask the initial color of the rubber composition. The process further includes causing a first laser beam of appropriate characteristics to interact in a first stage in order to reveal a first colored pattern part, followed in a second stage by a second laser beam of appropriate characteristics in order to reveal a second colored pattern part.
