Disclosed is a method for producing a cellulose ester film wherein a film-forming material containing the following components A-C is heated and melted, and a cellulose ester film is formed therefrom by melt-casting. A: a cellulose resin, B: an ester compound obtained by condensing an organic acid represented by Formula (1) and a polyalcohol, and C: an aliphatic polyester or an aliphatic-aromatic copolymer. 

Method of producing cellulose ester film, cellulose ester film, polarizing plate and liquid crystal display

An optical cellulose ester film comprising a cellulose ester (A); at least one ester based plasticizer (B) selected from ester based plasticizers composed of a polyhydric alcohol and a univalent carboxylic acid, or ester based plasticizers composed of a polyvalent carboxylic acid and a monohydric alcohol; at least one stabilizer (C) selected from the group consisting of a phenol based stabilizer, a hindered amine based stabilizer, or a phosphorous based stabilizer; and a hydrogen bonding solvent (D).

Optical cellulose ester film and manufacturing method thereof, and polarizing plate and liquid crystal display device

A method for manufacturing a polarizing plate protective film including the steps of: 1) mixing a cellulose ester resin and an organic additive to obtain a mixing composition, 2) placing the mixing composition in a mold to obtain an integral molding, and 3) heating to melt the integral molding so as to form the polarizing plate protective film, wherein the integral molding has a size of 1 mm&#xd7;1 mm&#xd7;1 mm to 20 mm&#xd7;20 mm&#xd7;20 mm, and the cellulose ester resin is contained in the integral molding in a state of particles.

Polarizing plate protective film and manufacturing method for the same

A transparent film for display substrate containing a cellulose ester, a plasticizer content in an amount of less than 1 percent, the aforementioned film being drawn 3 through 100 percent both in the direction of conveyance and across the width.

Transparent film for display substrate, display substrate using the film and method of manufacturing the same, liquid crystal display, organic electroluminescence display, and touch panel

A plasticizer comprising an ester compound produced by a condensation reaction of an organic acid represented by Formula (1) with a polyhydric alcohol having at least 3 hydroxyl groups in the molecule,
