Abstract: A process for producing a cellulose-ester-resin-containing protective film for polarizers through film formation by melt casting. The protective film diminishes long-period optical unevenness and suffers no unevenness even after long-term storage. Also provided are a protective film for polarizers, a polarizer employing the film, and a liquid-crystal display. The process for producing a protective film for polarizers is a process for producing by the melt casting method a polarizer-protective film containing a cellulose ester resin.

Abstract: A method for producing an optical film of the present invention includes: (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 2.0×104 to 5.0×105; (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.
