(EN) RESIN COMPOSITION FOR PROTECTIVE FILM
(FR) COMPOSITION DE RESINE POUR FILM PROTECTEUR
(JA) 保護膜用樹脂組成物
要約
(EN)
A resin composition for protective films which comprises an epoxy resin having two or more epoxy groups, a hardener, a hardening accelerator, a solvent, and a colloidal slurry of fine silica particles having an average particle diameter, as determined by conversion from the specific surface area, of 50 nm or smaller, a pH of 6 to 8, and an alkali metal content of 5 ppm or lower. The resin composition gives a protective film which satisfies adhesion and visible-light transmission, which are performances conventionally required. The protective film further has high surface smoothness even when the substrate surface has not been smoothed. The resin composition has satisfactory storage stability and does not cause liquid-crystal fouling. Furthermore, the cured film obtained from the resin composition has excellent high-temperature resistance, especially ITO resistance. The resin composition is hence suitable for use in forming a protective film for the colored resin films of color filters for liquid-crystal displays.
(FR)
La présente invention concerne une composition de résine pour films protecteurs, comprenant une résine époxyde présentant au moins deux groupes époxyde, un agent de durcissement, un accélérateur de durcissement, un solvant, une suspension colloïdale de fines particules de silice ayant un diamètre de particule moyen, tel que déterminé par conversion à partir de l'aire spécifique, de 50 nm ou moins, un pH de 6 à 8, et une teneur en métaux alcalins de 5 ppm ou moins. La composition de résine permet d'obtenir un film protecteur qui a des propriétés d'adhésion et de transmission de la lumière visible qui sont des aptitudes en général requises. Le film protecteur a de plus une rugosité de surface faible, même lorsque la surface du substrat n'a pas été lissée. La composition de résine a une aptitude au stockage satisfaisante et ne provoque pas d'altération des cristaux liquides. De plus, le film durci obtenu à partir de la composition de résine, a une excellente résistance aux températures élevées, en particulier une excellente résistance ITO. La composition de résine convient de ce fait à l'utilisation pour constituer un film protecteur pour films de résine colorés de filtres couleurs pour affichages à cristaux liquides.

 本発明は2つ以上のエポキシ基を有するエポキシ樹脂、硬化剤、硬化促進剤、溶剤及び比表面積換算法により測定された平均粒子径が50nm以下であり、PHが6~8であり、かつアルカリ金属分が5ppm以下のシリカ微粒子のコロイド状スラリーを含有する保護膜用樹脂組成物に関するもので、従来からの要求性能である密着性、可視光透過性を満足し、かつ基材表面が平坦化されていない場合であっても高い表面平滑性を有する保護膜を形成するとともに、該樹脂組成物は保存安定性が良く、液晶汚染性もなく、更に、該樹脂組成物から得られた硬化膜は高温耐性、特には耐ITO性に優れているので、該樹脂組成物は液晶表示用カラーフィルター着色樹脂膜の保護膜を形成するのに適する。
