Abstract:
(EN) For the purpose of providing a modifier for a cellulose ester resin whereby an optical film having low moisture permeability and minimal dimensional change in response to a change in humidity is obtained, the present invention provides a modifier for a cellulose ester resin, containing: an ester compound (X1) represented by formula (1) (where G in the formula represents a residue of a C2-10 polyhydric alcohol, A represents an aromatic monocarboxylic acid residue having a structure in which some or all hydrogen atoms in an aromatic ring are substituted with hydroxyl groups, and n represents an integer of 2 to 6); and a polyester polyol (X2) having a number-average molecular weight of 300-1,500 and a hydroxyl group value of 50-350, and having a C2-8 alkylene dicarboxylic acid residue or a C6-12 aromatic dicarboxylic acid residue, and a C2-6 alkylene glycol residue or a C4-6 oxyalkylene glycol residue in the main-chain backbone thereof.
(FR) L'invention concerne un modificateur pour une résine d'ester de cellulose, un film optique présentant une faible perméabilité à l'humidité et un changement dimensionnel minimal en réponse à un changement d'humidité étant obtenu. Le modificateur pour résine d'ester de cellulose selon l'invention contient : un composé de type ester (X1) représenté par la formule (1) : (où G dans la formule représente un radical d'un alcool polyhydrique en C2-10, A représente un radical d'acide monocarboxylique aromatique présentant une structure dans laquelle une partie ou la totalité des atomes d'hydrogène dans un cycle aromatique sont substitués par des groupes hydroxyle et n représente un nombre entier de 2 à 6) ; et un polyesterpolyol (X2) présentant un poids moléculaire numérique moyen de 300-1500 et un indice d'hydroxyle de 50-350 et présentant un radical d'acide (C2-8-alkylène)dicarboxylique ou un radical d'acide dicarboxylique aromatique en C6-12 et un radical de (C2-C6-alkylène)glycol ou un radical de (C4-6-oxyalkylène)glycol dans la chaîne principale correspondante.
(JA) 本発明は、透湿度が小さく、湿度の変化に伴う寸法の変化も少ない光学フィルムが得られるセルロースエステル樹脂用改質剤を提供することを目的として、下記式(1) (式中Gは、炭素原子数2~10の多価アルコールの残基である。Aは芳香環上の水素原子の一部乃至全部が水酸基に置換された構造を有する芳香族モノカルボン酸残基である。nは2~6の整数である。) で表されるエステル化合物(X1)と、主鎖骨格中に炭素原子数2~8のアルキレンジカルボン残基または炭素原子数6~12の芳香族ジカルボン酸残基と、炭素原子数2~6のアルキレングリコール残基または炭素原子数4~6のオキシアルキレングリコール残基とを有し、数平均分子量が300~1,500であり、水酸基価が50~350であるポリエステルポリオール(X2)とを含有するセルロースエステル樹脂用改質剤を提供する。
