<P>PROBLEM TO BE SOLVED: To provide an optical film having appropriate toughness as an optical film member. <P>SOLUTION: An optical film 1 according to the present invention includes a first layer 2 containing 50 wt.% or more of a thermoplastic elastomer resin, a second layer 3 laminated on a first surface 2a of the first layer 2 and containing 50 wt.% or more of an amorphous resin, and a third layer 4 laminated on a second surface 2b of the first layer 2 and containing 50 wt.% or more of an amorphous resin. The thermoplastic elastomer resin contained in the first layer 2 is a (meth)acrylic acid ester resin obtained by polymerization of a methacrylic acid ester monomer and an acrylic acid ester monomer. Each of the amorphous resins contained in the second layer 3 and the third layer 4 is a methacrylic acid ester resin obtained by polymerization of a methacrylic acid ester monomer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
