PHASE DIFFERENCE FILM LAMINATE METHOD FOR PRODUCING PHASE DIFFERENCE FILM LAMINATE AND METHOD FOR PRODUCING PHASE DIFFERENCE FILM

摘要

P1 layer consisting of a polyphenylene ether having a positive intrinsic birefringence value and a polystyrene-based polymer having a negative intrinsic birefringence value and having a syndiotactic structure, and an acrylic resin or alicyclic ring provided in contact with the P1 layer Retardation film laminated body formed by extending | stretching the pre-stretch film which has a P2 layer which consists of resin p2 containing a formula structure containing polymer, WHEREIN: Resin p1 WHEREIN: The weight ratio of content of the said polyphenylene ether / content of the said polystyrene polymer. Retardation film laminated body which is 35 / 65-45 / 55; Its production method; And a method for producing a retardation film using the same.
