  • Publication number: 20150301252
    Abstract: Provided are a method for preparing a thin polarizer, including forming a film laminate by bonding a non-stretched polyvinyl alcohol-based film having a thickness of 10 to 60 ?m to at least one surface of a non-stretched base film using an adhesive including an amine-based metal compound crosslinking agent and a polyvinyl alcohol-based resin containing an acetoacetyl group, and stretching the film laminate so as to allow the polyvinyl alcohol-based film to have a thickness of 10 ?m or less, and a thin polarizer manufactured through the same.

  • Patent number: 9158051
    Abstract: A method of manufacturing a thin film polarizer includes forming a film laminate by alternately bonding two or more non-oriented polymer films and two or more non-oriented polyvinyl alcohol-based films to each other using attractive force or an adhesive layer, orienting the film laminate so that the polyvinyl alcohol-based film has a thickness of 10 ?m or less after the orienting of the film laminate, and separating the polymer films and the polyvinyl alcohol-based films of the oriented film laminate from each other.

  • Publication number: 20150224746
    Abstract: Provided is a stretched laminate for manufacturing a thin polarizer while increasing the degree of orientation of a polyvinyl alcohol-iodine complex without problems such as breakage. In addition, there are provided a method of manufacturing a thin polarizer having superior optical characteristics by using the stretched laminate, a thin polarizer manufactured by the method, and a polarizing plate including the thin polarizer.

  • Patent number: 6481260
    Abstract: A device for embossing metal pipe is disclosed. The device includes a core having a plunger hole and a plurality of core pass through holes perpendicular to the plunger hole. The device also includes a plunger for moving through the plunger hole to push the punches in the core pass through holes selectively away in a direction perpendicular to the axis of the core.
