  • Patent number: 7655289
    Abstract: The present invention generally relates to optical films useful in the manufacture of polarizer plates, an improved method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to an optical film composite comprising a temporary carrier substrate having a center area and an edge area, said substrate having coated thereon an optical film wherein the adhesive strength between the optical film and the substrate is greater at the edge area than at the center area of the substrate.

  • Patent number: 7279060
    Abstract: The invention generally relates to polymer films used as protective cover sheets for polarizer plates, a method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to cover sheet composites having a removable, carrier substrate and, optionally, a strippable, protection layer that protects the cover sheet from abrasion and dirt during the manufacture of the cover sheet and polarizer plates.

  • Patent number: 7252733
    Abstract: The invention generally relates to polymer films used as protective cover sheets for polarizer plates, a method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to a cover sheet composite having a removable, carrier substrate and a cover sheet comprising a low birefringence polymer film and a layer that promotes adhesion to polyvinyl alcohol on the same side of the carrier substrate as the low birefringence polymer film. The guarded cover sheet of the invention is less susceptible to defects due to dirt and abrasion during the manufacture of the cover sheet and polarizer plates. In addition, the cover sheet has excellent adhesion to polyvinyl alcohol-containing dichroic films and eliminates the need to alkali treat the cover sheet prior to lamination to the dichroic films.

  • Patent number: 7075606
    Abstract: A method for manufacturing an optical compensator (5) on a transitional substrate (8) comprises applying a first orientation layer (20) to the transitional substrate. The first orientation layer (20) is then aligned and a first anisotropic liquid crystal material (30) is applied on the first orientation layer. In one embodiment, a retardation layer (10) is located between the transitional substrate (8) and the first orientation layer (20).

  • Patent number: 6143484
    Abstract: The present invention is a method for stabilizing a photographic coating melt. The photographic melt includes an aqueous medium and a dispersed liquid organic phase containing an ultraviolet ray absorbing compound, and an emulsion containing silver halide particles having an average equivalent circular diameter of from 0.03 to 0.10 microns. The photographically useful ultraviolet ray absorber compound is soluble in a liquid organic phase and substantially insoluble in water. The method includes the step of adding to the emulsion containing silver halide particles a sufficient amount of surfactant to passify surfaces of the silver halide particles. The present invention is also a method of preparing a photographic coating melt. A dispersion is prepared which includes an aqueous medium, a dispersed liquid organic phase and an ultraviolet ray absorber compound wherein the ultraviolet ray absorber compound is soluble in the dispersed liquid organic phase and substantially insoluble in water.
