Title:
光学材料用樹脂組成物、光学フィルム及び画像表示装置
Document Type and Number:
Japanese Patent JP7375493
Kind Code:
B2
Abstract:
To provide a resin composition for optical material which can produce an optical film whose in-plane and out-of-plane phase differences are adjusted in a negative direction without impairing heat resistance.SOLUTION: A resin composition for optical material contains a cyclic olefin resin, and a styrene copolymer that is a styrene-acrylic copolymer or a styrene-maleimide copolymer. When a glass transition temperature of the cyclic olefin resin is represented by Tg1 and a glass transition temperature of the styrene copolymer is represented by Tg2, Tg1-5≤Tg2 is satisfied.SELECTED DRAWING: None
