Method for producing cellulose ester film, cellulose ester film, polarizing plate, and liquid crystal display device |
| abstract |
An object of the present invention is to provide a method for producing a cellulose ester film excellent in transparency durability in which deterioration of film transparency is suppressed even under severe thermal environment changes. A cellulose ester film comprising a step of preparing a dope containing at least a cellulose ester (A), and a step of adding an additive solution containing a cellulose ester (B) different from the cellulose ester (A) to the dope. The cellulose esters (A) and (B) have a specific relationship with the type of acyl group and the degree of substitution, and the mass ratio of the cellulose ester (B) is 0.03 of the total cellulose ester. % To 5.0%, and the additive liquid containing the cellulose ester (B) contains fine particles having an average primary particle size of 10 nm or less, and the web is stretched at least 1.4 times in the width direction. The manufacturing method of the cellulose-ester film characterized by these. [Selection figure] None |
