Title (EN) COATED FINE PARTICLES OF ALKALINE-EARTH METAL COMPOUND, DISPERSION IN ORGANIC SOLVENT, RESIN COMPOSITION, AND IMAGE DISPLAY DEVICE
(FR) MICROPARTICULES DE COMPOSÉ ALCALINO-TERREUX REVÊTUES, DISPERSION DE SOLVANT ORGANIQUE, COMPOSITION DE RÉSINE, ET DISPOSITIF D’AFFICHAGE D’IMAGE

Abstract:
(EN) In order to provide an optical film in which the birefringence of the polymer has been diminished and the transparency is ensured, coated fine particles of an alkaline-earth metal compound are provided, the particles having high dispersibility during film formation at high temperatures. The coated fine particles of an alkaline-earth metal compound comprise fine particles of an alkaline-earth metal compound and a surface-treating agent with which the surface of the fine particles has been coated. When the coated fine particles are examined by TG-DTA in the air and the mass of the surface-treating agent at the time of TG-DTA initiation is taken as 100 mass%, then the loss in mass of the surface-treating agent in the temperature range of 100 to 300°C is 30 mass% or less.
(FR) L’invention fournit des microparticules de composé alcalino-terreux revêtues qui tout en annulant la biréfringence d’un polymère, sont destinées à fournir un film optique dont la transparence est garantie, et présentent une dispersibilité élevée lors d’une formation de film à haute température. Ces microparticules de composé alcalino-terreux revêtues sont telles que la surface de microparticules de composé alcalino-terreux est revêtue par un agent de traitement de surface. Lorsqu’une analyse thermo-gravimétrique et thermique différentielle (TG-DTA) est effectuée dans l’atmosphère, et quand la masse d’agent de traitement de surface au commencement de cette annalyse équivaut à 100% en masse, le taux de réduction de masse de l’agent de traitement de surface dans une plage de température de 100°C à 300°C, est inférieur ou égal à 30% en masse.
(JA) 高分子の複屈折を打ち消しつつ、透明性が確保された光学フィルムを提供するため、高温での成膜時における分散性が高い被覆アルカリ土類金属化合物微粒子を提供すること。被覆アルカリ土類金属化合物微粒子は、アルカリ土類金属化合物微粒子の表面が表面処理剤で被覆されており、大気雰囲気中でTG-DTAを行うと、TG-DTA開始時の表面処理剤の質量を100質量%としたとき、100℃~300℃の温度範囲での表面処理剤の質量減少率が30質量%以下である。
