CELLULOSE ACETATE FILM, AND POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE WHICH ARE MADE USING SAME |
摘要 |
<p>Provided is a cellulose acetate film which has excellent retardation properties and exhibits low haze even under high-temperature and high-humidity conditions and which, in an alkaline saponification step, causes little dissolution of the film itself or additives in a saponifying liquid. The cellulose acetate film is characterized by comprising: a cellulose acetate which has an acetyl substitution degree of 2.0 to 2.5; and 5 to 15% by mass (relative to the cellulose acetate) of a component which contains a compound represented by general formula (1) wherein m is 0 and a compound represented thereby wherein m is more than 0 at a ratio of 45:55 to 0:100. In general formula (1), G is a mono- or di-saccharide residue; X 1 is -O-; R 1 is -CO-R 2 ; R 2 is an aliphatic or aromatic group; m represents the total number of hydroxyl groups directly bonded to the mono- or di-saccharide residue; and n represents the total number of OR 1 groups directly bonded to the mono- or di-saccharide residue, with the proviso that m and n satisfy the relationships: 3 ‰¤ m+n ‰¤ 8 and n is not 0.</p> |
