    Abstract: A beaded light dispersing film has a substrate layer, and an optically transparent layer, having a predetermined thickness, disposed over a side of the substrate layer. Optically transmitting beads are arranged to penetrate at least partially into the transparent layer to define clear apertures at interfaces between the beads and the transparent layer. The bead radius is greater than the predetermined thickness. An absorbing layer is disposed on the transparent layer, in interstices between the beads. A method of manufacturing the film includes disposing optically transparent beads partially in an optically transparent layer disposed over a transparent substrate layer. The optically transparent layer has a thickness less than half a diameter of a transparent bead. An absorbing layer overlies the optically transparent layer.

    CPC classification number: G03B21/62

    Abstract: An optically dispersing film for a rear projection system includes reflecting surfaces disposed so as to reflect light passing therethrough into at least one dispersion plane. The reflecting surfaces are formed by structures, of a first refractive index, disposed within a layer of material having a second refractive index. The structures have light absorbing bases at the viewing side of the film. In some embodiments, the reflecting surfaces are disposed at one or more angles so as to reflect light into a number of different directions. In other embodiments, the layer of material having the second refractive index includes diffusing particles that diffuse the light. The film permits the asymmetric dispersion of image light in a rear projection system, so that the light may be selectively directed towards the viewer.

    Abstract: A method comprising the following steps:(a) creating a thermal transfer donor sheet by vapor depositing a colorant layer onto a support;(b) contacting a receptor sheet with the donor sheet such that the colorant layer is in intimate contact with the receptor sheet, wherein at least one of the donor and receptor sheets comprises a radiation-absorbing material;(b) imagewise exposing the contacted sheets to radiation of a wavelength absorbed by the radiation-absorbing material, thereby causing heating in the exposed regions, said heating causing thermal transfer of colorant from the donor sheet to the receptor sheet in an imagewise fashion.

    Abstract: A process is described for the formation of a color image on a substrate comprising the steps of:a) providing a donor element comprising element comprises a carrier substrate, color containing photohardenable layer, and photopolymerizable adhesive layer in which the unexposed photopolymer has a viscosity at 25.degree. C. of less than 100,000 cps,b) adhering said photopolymer adhesive layer to a first substrate,c) irradiating said photopolymer adhesive in an imagewise distribution of radiation to polymerize said adhesive in an imagewise distribution, andd) stripping said element from said first substrate leaving an imagewise distribution of said color containing layer secured to said substrate. This process can be used to form any type of color image and is particularly useful in the formation of color proofs. Both positive and negative images can be provided, a positive image on the element and a negative image on the substrate.

    Abstract: Laser-addressable thermal transfer materials for producing color proofs, printing plates, films, printed circuit boards, and other media are disclosed. The materials contain a substrate coated thereon with a propellant layer wherein the propellant layer contains a material capable of producing nitrogen (N.sub.2) gas at a temperature of preferably less than about 300.degree. C.; a radiation absorber; and a thermal mass transfer material. The thermal mass transfer material may be incorporated into the propellant layer or in an additional layer coated onto the propellant layer. The radiation absorber may be employed in one of the above-disclosed layers or in a separate layer in order to achieve localized heating with an electromagnetic energy source, such as a laser. Upon laser induced heating, the transfer material is propelled to the receptor by the rapid expansion of gas. The thermal mass transfer material may contain, for example, pigments, toner particles, resins, metal particles, monomers, polymers, dyes, or combinations thereof.Also disclosed is a process for forming an image as well as an imaged article made thereby.
