    • The present invention provides an acid anhydride ester obtained by esterifying cyclohexane-1,2,4-tricarboxylic acid-1,2-anhydride and a composition of the ester, and a heat-curable resin composition and a cured product of the composition. _Provided is an epoxy resin composition using the acid anhydride ester as a curing agent for an epoxy resin, the epoxy resin composition having, for example, the following properties (1), (2), and (3): (1) the epoxy resin composition has a low viscosity at room temperature, so the components of the composition can be favorably blended with each other, (2) the acid anhydride ester has a low vapor pressure at curing temperature, so no evaporation loss occurs after curing, and the intended design of blend is capable, and (3) a cured product to be made from the composition is colorless and transparent, and changes its color to a small extent even when the product is irradiated with light or heated for a long time period. The composition is suitably used as, for example, an encapsulant for a photoelectric conversion element such as a blue LED or a white LED, a molded article, a coating, or an adhesive.
    • 本发明提供通过酯化环己烷-1,2,4-三羧酸-1,1-酐和酯的组合物得到的酸酐酯,以及热固性树脂组合物和该组合物的固化物。 提供使用酸酐酯作为环氧树脂固化剂的环氧树脂组合物,该环氧树脂组合物具有例如以下性质(1),(2)和(3):(1)环氧树脂 树脂组合物在室温下的粘度低,因此可以有利地将组合物的组分相互混合,(2)酸酐在固化温度下蒸气压低,固化后不会发生蒸发损失, 共混物的预期设计是能够的,并且(3)由该组合物制成的固化产物是无色透明的,并且即使当产品被光照射或长时间加热时也将它的颜色变化很小。 该组合物适合用作例如蓝色LED或白色LED的光电转换元件的密封剂,成型品,涂层或粘合剂。

    • Provided is a gas-barriering coated film obtained by coating a gas barriering layer on at least one face of a flexible film or an inorganic-deposited polymer film, wherein the above gas-barriering layer is a polyurethane resin-cured material formed from a composition comprising an active hydrogen-containing compound (A) and an organic polyisocyanate compound (B), and 20% by weight or more of a skeletal structure represented by Formula (1) is contained in the above resin-cured material. The gas-barriering coated film of the present invention is excellent in various performances such as a layer-to-layer adhesive property, a gas barriering property at a high humidity, a bending resistance and a retort treating resistance in addition to a high gas barriering property, and therefore it is applied to various uses including packing materials for food and medicines to which a high gas barriering property is required.
    • 提供一种通过在柔性膜或无机沉积聚合物膜的至少一个表面上涂覆阻气层而获得的气体阻挡涂布膜,其中上述阻气层是由组合物形成的聚氨酯树脂固化材料 包含含活性氢的化合物(A)和有机多异氰酸酯化合物(B),并且在上述树脂固化材料中含有20重量%以上由式(1)表示的骨架结构。 本发明的阻气性涂膜除了高阻气性以外还具有各种性能,例如层间粘合性,高湿度下的阻气性,耐弯曲性和蒸煮处理电阻 属性,因此适用于需要高气体阻塞性的食品,药品的包装材料等各种用途。
