The invention relates to a protective cover sheet comprising a low birefringence protective polymer film and a layer that promotes adhesion to poly(vinyl alcohol), the protective cover sheet comprising at least one functional layer containing a UV-absorbing polymer.

Protective cover sheet comprising a UV-absorbing layer for a polarizer plate and method of making the same

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.

Optical film composite having spatially controlled adhesive strength

A method of bead coating a liquid composition onto the surface of a moving web is taught which provides uniform coatings over a wider range of operating parameters including new coating windows. In addition, the bead coating method typically demonstrates a reduction in coating sensitivity to vacuum pressure noise below the coating bead. The method comprises the steps of forming a bottom layer on a slide surface of a slide bead coating apparatus with a pseudoplastic liquid composition having a viscosity between 8 and 200 centipoises at a shear rate of 100 sec and a viscosity below 10 centipoises at a shear rate of 100,000 sec ; forming at least one other liquid coating layer above the bottom layer on the slide surface of the slide bead coating apparatus; establishing a coating bead between a lip of the slide bead coating apparatus and the moving web supported on a back-up roller, generating an electrostatic field in an air gap between the coating bead and the moving web just prior to a dynamic wetting line by creating a potential difference across the air gap of between about 300 and about 2000 volts.
