Abstract:
Disclosed herein is an adhesive composition for transporting a flexible substrate, which is used to manufacture a flexible display device using a flexible substrate such as a plastic substrate by using a conventional line for manufacturing a liquid crystal display device comprising a glass substrate. The present invention provides an adhesive composition for transporting a flexible substrate, which includes 100 parts by weight of an adhesive for transporting a flexible substrate and 0.001 to 5 parts by weight of an antistatic agent, an adhesive sheet containing the composition, and a method of transporting a flexible substrate using the same.
Abstract:
Flex circuits for use in ink jet printers. In particular, flex circuits for use in ink jet printers that include a polyester material layer supporting a plurality of metal conductors, with the polyester material being a material suitable for use in an ink environment with lower ink permeability and low moisture and ink absorption than polyimide (PI) material. The polyester layer having low ink permeability and moisture and ink absorption to prevent: catastrophic "ink shorting of conductors" failures; adhesion failures; corrosion failures by direct ink contact with the conductors; and material degradation failures that may result if any of the materials are degraded by or react with the ink. Preferably, the polyester material is polyethylene naphthalate (PEN). The polyester base layer is suitable for use in many major flex circuit construction types, including: both adhesive-less and adhesive-based circuits; and one-metal and two-metal layer circuits. Also, a method of producing an improved splice in a continuous Tab Automated Bonding (TAB) style strip of circuits, using a suitable polymer material layer, that is stronger per area than other splices.
Abstract:
A composite film which comprises a film (A) formed of a ring-structure polymer having repeating units formed by the ring-opening type or addition type polymerization of a ring-structure monomer and a film (B) formed of a polycondensation type polymer and wherein at least two layers are adjacent to each other directly or via an adhesive layer.
Abstract:
A prepreg useful for the production of composites and copper foil-laminated or similar printed circuit boards having a high heat resistance and high dimension stability, comprises a syndiotactic vinylaromatic polymer fibrous base material and a thermosetting resin composition.
