Cover sheet comprising an adhesion promoting layer for a polarizer and method of making the same |
摘要 |
The invention relates to a protective cover sheet comprising a low birefringence protective polymer film and a layer containing a water-soluble polymer and polymer particles that promotes adhesion to poly(vinyl alcohol). The cover sheet has excellent adhesion to poly(vinyl alcohol)-containing dichroic polarizing films and eliminates the need to alkali treat the cover sheet prior to lamination to the dichroic films, thereby simplifying the process to manufacture polarizing plates.
