摘要： 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.

摘要： The present invention comprises a polyester film support in which the surface has been subjected to an energetic treatment with nitrogen plasma to produce amine groups on the polyester surface. The treated surface is then coated with a dilute solution of amine reactive hardener and gelatin. After drying the hardener/gelatin coated support a photographic emulsion is coated on the surface. The resulting film element has excellent adhesion of the photographic emulsion after photoprocessing, and it is safer to coat and handle than previously known methods involving grafting of hardener directly to the support.
