Abstract: front page image
(EN)Disclosed is an optical film produced by stretching a cellulose ester containing needle-like fine particles and at least one additive selected from polyesters, polyhydric alcohol esters, polyvalent carboxylates and polymers obtained by polymerizing ethylenically unsaturated monomers. This optical film is characterized in that the needle-like fine particles exhibit negative birefringence with respect to the stretching direction.
(FR)La présente invention concerne une pellicule optique produite en étirant un ester de cellulose contenant des particules fines en forme d'aiguilles et au moins un additif sélectionné parmi les polyesters, les esters d’alcools polyhydriques, les carboxylates polyvalents et les polymères obtenus par polymérisation éthylénique de monomères insaturés. Cette pellicule optique est caractérisée en ce que les fines particules en forme d’aiguille présentent une biréfringence négative par rapport à la direction d’étirement.
(JA)ポリエステル、多価アルコールエステル、多価カルボン酸エステル及びエチレン性不飽和モノマーを重合して得られたポリマーから選ばれる少なくとも1種の添加剤及び,針状微粒子を含有するセルロースエステルを延伸して製造した光学フィルムであって、該針状微粒子が延伸方向に対して負の複屈折性を示すことを特徴とする光学フィルム。
