  • Publication number: 20070243339
    Abstract: Disclosed is an optical film comprising a layer containing preformed porous polymer particles with a specific surface area of 10 m2/g or greater and a median diameter from 1-20 ?m in a radiation cured binder. Such a film provides an improved antiglare film with a minimal transmission haze penalty.

  • Publication number: 20070111145
    Abstract: Thermally developable materials that comprise a support have a conductive backside layer that has increased conductive efficiency. Conductivity is provided by non-acicular metal antimonate particles that are present in an amount greater than 55 and up to 85 dry weight % at a coverage of from about 0.06 to about 0.5 g/m2, and the ratio of total binder polymers in the backside conductive layer to the non-acicular metal antimonate particles is less than 0.75:1 (dry weights). The level of conductive particles is reduced from previous uses without an unacceptable loss in conductivity. In addition, the dry thickness of the conductive layer is considerably reduced.

  • Publication number: 20060210931
    Abstract: Thermally developable materials including photothermographic and thermographic materials having an outermost backside layer that includes amorphous silica particles having a narrow particle size distribution. The narrower particle size distribution provides reduced haze and increased surface roughness that reduces blocking and machine feeding at comparable weight percent. The materials can also include conductive layers underneath the outermost backside layer.

  • Publication number: 20060194158
    Abstract: The use of metal antimonates at high metal antimonate to binder ratios in buried backside conductive layers of thermographic and photothermographic materials allows the use of thin backside overcoat layers. The combination provides antistatic constructions having excellent antistatic properties that show less change in resistivity with changes in humidity. The thin backside overcoat layer serves to protect the buried antistatic layer.

  • Publication number: 20060166151
    Abstract: Backside conductive layers with increased conductive efficiency can be provided for thermally developable materials by formulating hydrophilic metal oxide clusters in a hydrophobic environment using low shear mixing conditions. The dry thickness and coating weight of the conductive layer are thereby reduced.

  • Publication number: 20050196552
    Abstract: The invention provides an optical film comprising a transparent support with an antireflection layer substantially conformed in shape to the surface underlying the layer, the antireflection layer containing a binder polymer having dispersed polymer particles which are nanovoided so as to have a surface area greater than 50 m2/gm and which fill 64% or less of the layer volume. The film provides improved anti-reflection without the expected increase in transmission haze.

  • Publication number: 20050167896
    Abstract: A method of fabricating a polymeric film includes adsorbing an ammonium salt surfactant over a plurality of polymer beads. The method also includes adding the polymer beads to a polymer solution, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads. Additionally, a polymeric film includes a plurality of polymer beads each having an outer surface. The polymeric film also includes an ammonium salt surfactant disposed over each of the outer surfaces, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads.

  • Publication number: 20050123742
    Abstract: Disclosed is an integral film comprising a transparent polymeric substrate having a surface bearing polymeric beads, wherein the swell ratio, the size, and the laydown of the beads are selected so as to provide both a one sided static friction coefficient of not more than 0.68 and an internal haze value of not more than 0.1. The film provides an improved combination of slip and optical properties.
