Method for producing cellulose ester optical film and cellulose ester optical film |
abstract |
PROBLEM TO BE SOLVED: To provide a cellulose ester optical film formed by a melt casting method having sufficient optical properties and mechanical properties as an optical film and increasing the effective utilization rate of resources. A method for producing a cellulose ester optical film in which a mixture containing unheated cellulose ester A, heated and melted recovered cellulose ester B, and at least one additive is heated and melt-extruded. And adding the mixture containing the unheated cellulose ester A and the at least one additive to start heating and melting, and then adding and melting all or part of the recovered cellulose ester B to produce the mixture. A method for producing a cellulose ester optical film. [Selection figure] None |
