Method for producing optical film, optical film, polarizing plate and liquid crystal display device |
| abstract |
The purpose of the present invention is to provide a method for producing an optical film having a reduced haze by suppressing coloring and the formation of gel-like foreign bodies. A method for producing an optical film of the present invention comprises: (1) a step for obtaining a (meth)acrylic resin by copolymerizing methyl methacrylate and a copolymerizable monomer containing an acryloyl morpholine in the presence of a polymerization initiator and a chain transfer agent; and (2) a step for obtaining an optical film by melt extruding a resin composition that contains the thus-obtained (meth)acrylic resin and a cellulose ester resin at a (meth)acrylic resin:cellulose ester resin ratio of from 95:5 to 30:70. The (meth)acrylic resin obtained in step (1) is characterized in that: (a) the weight average molecular weight (Mw) thereof is from 2.0 × 10 4 to 5.0 × 10 5 ; (b) the total amount of the remaining methyl methacrylate and the remaining copolymerizable monomer is 0.05-1% by mass; (c) the amount of the remaining polymerization initiator is 0.01-0.5% by mass; and (d) the amount of the remaining chain transfer agent is 0.01-0.5% by mass. |
