    • In accordance with this invention, a photographic film especially suited for motion imaging film applications such as motion picture film or television film has on one side of a support material, in order, a process surviving, electrically conductive subbing layer, a photographic emulsion, and a protective overcoat; and on the opposite side a carbon black-containing backing layer, and optionally, a lubricant that overlies the backing layer. The carbon black-containing layer provides antihalation and antistatic protection for the unprocessed film. The conductive subbing layer retains its antistatic properties after processing so that the motion imaging film is protected from the generation of static charge after the carbon black-containing layer is removed during processing. The conductive subbing layer has a resistivity of less than 5.times.10.sup.9 .OMEGA./.quadrature. after film processing.
    • 根据本发明,特别适用于诸如电影胶片或电视胶片的运动成像胶片应用的照相胶片在一个支撑材料的一侧上,依次为工艺存活,导电底胶层,照相乳剂和 保护性外套; 并且在相对侧具有含炭黑的背衬层,以及任选的覆盖在背衬层上的润滑剂。 含炭黑层为未加工的膜提供防晕和抗静电保护。 导电性底层在加工后保持其抗静电性,使得运动成像膜在加工过程中除去含炭黑层后,不受静电荷的产生。 导电胶层的电阻率小于5×10 9欧姆/平方厘米。

    • The present invention provides a composite light guiding plate comprising a light guiding layer comprising an incident face for receiving light from at least one light source, a light guiding output surface that is also generally orthogonal to the incident face, a featured surface, opposite the light-guiding output surface and generally orthogonal to the input face for redirecting light through the light guiding output surface. Further, the featured surface comprises a plurality of rows of linear prismatic structures extended in a length direction that is substantially perpendicular to the incident face and having height and width dimensions of 10 to 200 microns and wherein the length-to-width aspect ratio of the linear prismatic structures is greater than 100:1 the thickness of the light guiding layer is less than 1 mm. Further, the plate is formed from polymeric materials comprising polyesters, amorphous polyesters, polyarylates, polycarbonates, polyamides, polyether-amides, polyamide-imides, polyimides, polyetherimides, cyclic olefin polymers, impact-modified polymethacrylates, polyacrylates, polyacrylonitrile, polystyrenes, polyethers, cellulosics, sulfur-containing polymers and blends or alloys of two or more polymers or copolymers thereof. Additionally, the plate comprises a light extraction layer comprising an input surface having a plurality of protruding light extraction features that have tips that are bonded to the light-guiding output surface of the light guiding layer and provide optical contact between the light guiding and light extraction layers and an illumination output surface for providing light output from the composite illumination plate. Further, the thickness of the light extraction layer is less than 1 mm and wherein one or more channels of air or other gas are sandwiched between the light guiding layer and the light extraction layer.
