摘要： A cellulose acylate film comprising a cellulose acylate satisfying formulae (I) to (III), 2.0≦A+B≦2.8 Formula (I) 0.3≦A≦1.4 Formula (II) 0.6≦B≦2.5 Formula (III) wherein in formulae (I) to (III), A is the substitution degree by an acetyl group to the hydroxyl group of the glucose unit of the cellulose acylate, and B is the substitution degree by an acyl group having a carbon number of 3 or more to the hydroxyl group of the glucose unit of the cellulose acylate, and wherein a width of a cast film when casting a dope comprising the cellulose acylate is from 2,000 to 4,000 mm, and the cellulose acylate film is formed through the cast film.
摘要翻译：包含满足式（I）至（III）的纤维素酰化物的纤维素酰化物膜，<？in-line-formula description =“In-line Formulas”end =“lead”？> 2.0 <= A + B <= 2.8 （I）<？in-line-formula description =“In-line Formulas”end =“tail”？> <？in-line-formula description =“In-line formula”end =“lead”？> 0.3 <= A <= 1.4公式（II）<？in-line-formula description =“In-line Formulas”end =“tail”？> <？in-line-formula description =“In-line Formulas”end =“lead” 其中，式（I）〜（III）中，A为取代基，式（I）〜（III）中，A为取代基乙酰基与酰化纤维素的葡萄糖单元的羟基的相对程度，B是碳原子数为3以上的酰基与纤维素酰化物的葡萄糖单元的羟基的取代度，以及其中浇铸含有纤维素酰化物的涂料的流延薄膜的宽度为2,000〜4000mm，并且所述纤维素酰化物薄膜形成为t 通过流行电影。
