Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive polarization plate which includes a transparent protection film only on one surface of a polarizer and includes an adhesive layer on the other surface thereof, the adhesive polarization plate satisfying durability even under severe environment at a low temperature and a high temperature. SOLUTION: The adhesive polarization plate includes the transparent protection film (E) provided on only one surface of the polarizer (P) through an adhesive layer (G) and includes the adhesive layer (B) provided on the other surface of the polarizer (P) through a protection layer (H) having a modulus of elasticity in tension of ≥100 MPa.

Abstract:
Provided is a pressure-sensitive adhesive polarizing plate, including: a polarizer (P); a transparent protective film (E) provided on only one side of the polarizer (P) with an adhesive layer (G) interposed therebetween; a pressure-sensitive adhesive layer (B) provided on another side of the polarizer (P) with a protective layer (H) having a tensile modulus of 100 MPa or more interposed therebetween, wherein the protective layer (H) is made from a protective layer-forming agent (H') that is a cyanoacrylate-based layer-forming agent, an epoxy-based layer-forming agent, an isocyanate-based layer-forming agent, or an acryl-based layer-forming agent. The pressure-sensitive adhesive polarizing plate satisfies durability even under harsh environments at a low temperature and a high temperature.
Abstract:
The pressure-sensitive adhesive product has a constitution wherein a pressure-sensitive adhesive layer is formed on at least one surface of a substrate, the substrate being formed from a resin composition containing an acrylonitrile-styrene copolymer and an acrylonitrile-styrene-acrylic rubber copolymer as main components and the weight ratio of the acrylonitrile-styrene copolymer to the acrylonitrile-styrene-acrylic rubber copolymer being 90/10 to 20/80. The above resin composition preferably has a form where the acrylonitrile-styrene-acrylic rubber copolymer is dispersed in the acrylonitrile-styrene copolymer.
