发明名称 LAMINATED ACRYLIC RESIN FILM, POLARIZER PROTECTIVE FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY
摘要 <P>PROBLEM TO BE SOLVED: To provide a laminated acrylic resin film, which is superior in optical characteristics, transparency, zero defect, heat resistance, tenacity and working capability, a polarizing plate protective film employed thereof, a polarizing plate and a liquid crystal display. <P>SOLUTION: This laminated acrylic resin film includes an acrylic resin &alpha; containing glutaric anhydride unit having structural formula (1) and acrylic elastomer particles &beta;. When let a B layer be a layer including acrylic elastomer particles &beta; and an A layer be a layer with no acrylic elastomer particles included, this resin film is so constituted as to be produced by alternately laminating the A layer and the B layer in the direction of thickness by at least three sets of layers and, at the same time, every surface of the set is composed of the A layer having at least 1 &mu;m and the total thickness of the A layers is set to be &le;30% of the total thickness of the film. <P>COPYRIGHT: (C)2009,JPO&INPIT
