Abstract:
(EN) A cellulose ester film containing a polyester represented by the following general formula (1) or (2), characterized in that the in-plane retardation (Ro) and the thickness-direction retardation (Rt) as measured at ordinary temperature and ordinary humidity (23°C, 55% RH) are 0 to 5 nm and -20 to 10 nm, respectively. General formula (1) B1-(G-A-)mG-B1 (In the formula, B1 represents a monocarboxylic acid; G represents a dihydric alcohol; A represents a dibasic acid; none of B1, G, and A contains an aromatic ring; m indicates the number of repetitions; and B1's and G's each may be the same or different.) General formula (2) B2-(A-G-)nA-B2 (In the formula, B2 represents a monohydric alcohol; G represents a dihydric alcohol; A represents a dibasic acid; none of B2, G, and A contains an aromatic ring; n indicates the number of repetitions; and B2's and G's each may be the same or different.)
(FR) La présente invention concerne un film d'ester de cellulose contenant un polyester représenté par la formule générale (1) ou (2), caractérisé en ce que le retard dans le plan (Ro) et le retard dans la direction de l’épaisseur (Rt) lorsqu’ils sont mesurés à une température ordinaire et sous humidité ordinaire (23 °C, HR de 55 %) sont de 0 à 5 nm et de -20 à 10 nm, respectivement. Formule générale (1) B1-(G-A-)m-G-B1 (dans la formule, B1 représente un acide monocarboxylique ; G représente un diol ; A représente un diacide ; aucun parmi B1, G et A ne contient un noyau aromatique ; m indique le nombre de répétitions ; et chacun des groupes B1 et G peut être identique ou différent.) Formule générale (2) B2-(A-G-)nA-B2 (dans la formule, B2 représente un monoalcool ; G représente un diol ; A représente un diacide ; aucun parmi B2, G et A ne contient un noyau aromatique ; m indique le nombre de répétitions ; et chacun des groupes B2 et G peut être identique ou différent.)
(JA)  下記一般式(1)または(2)で表されるポリエステルを含有するセルロースエステルフィルムであって、常温常湿(23°C、55%RH)における面内のリターデーション(Ro)が0~5nm、厚み方向のリターデーション(Rt)が-20~10nmであることを特徴とするセルロースエステルフィルム。  一般式(1)  B1-(G-A-)mG-B1 (式中、B1はモノカルボン酸を表し、Gは2価のアルコールを表し、Aは2塩基酸を表す。B1、G、Aはいずれも芳香環を含まない。mは繰り返し数を表す。複数のBおよびGは同じでも異なってもよい。)  一般式(2)  B2-(A-G-)nA-B2 (式中、B2はモノアルコールを表し、Gは2価のアルコールを表し、Aは2塩基酸を表す。B2、G、Aはいずれも芳香環を含まない。nは繰り返し数を表す。複数のBおよびGは同じでも異なってもよい。)
