摘要	Provided are an epoxy resin composition including acid anhydrides (A) and epoxy resins (B), in which: (a) cyclohexane-1,2,4-tricarboxylic acid-1,2-anhydride accounts for 50 to 90 mass % of the acid anhydrides (A); (b) an alicyclic epoxy resin compound accounts for 30 to 90 mass % of the epoxy resins (B) and an epoxy resin compound represented by the following general formula (1) accounts for 10 to 50 mass % of the epoxy resins (B); and (c) contents of the acid anhydrides (A) and the epoxy resins (B) are such that a blending equivalent ratio between the acid anhydrides and the epoxy resins ranges from 0.4 to 0.7, a cured product of the composition, and a light-emitting diode. The epoxy resin composition has the following characteristics. That is, (1) the composition has a low viscosity after the mixing, a low degree of viscosity increase in standing at room temperature, and excellent workability, (2) the composition has satisfactory curability even when no curing accelerator is added, and (3) a cured product is colorless and transparent, has crack resistance, and changes its color to a small extent with long-term light irradiation and heating. The composition is suitable for an encapsulant for a photoelectric conversion element such as a blue LED or white LED. (In the formula, R's each independently represent a hydrogen atom or a methyl group, m represents an integer of 1 to 3, and n represents an integer of 2 to 8.)
其他摘要	本发明提供一种环氧树脂组合物，其包含酸酐（A）和环氧树脂（B），其中：（a）环己烷-1,2,4-三羧酸-1,2-酐占50-90质量％。酸酐（A）; （b）脂环族环氧树脂组合物占环氧树脂（B）的30~90质量％，下述通式（1）所示的环氧树脂组合物占环氧树脂（B）的10~50质量％。 ; （c）酸酐（A）和环氧树脂（B）的含量使得酸酐和环氧树脂的混合当量比为0.4-0.7，组合物的固化产物和光 - 发光二极管。环氧树脂组合物具有以下特征。即，（1）该组合物在混合后具有低粘度，在室温下保持低粘度，并且具有优异的可加工性。（2）即使不添加固化促进剂，该组合物也具有令人满意的固化性，（ 3）固化产物无色透明，具有抗裂性，并且通过长期光照射和加热可以在很小程度上改变其颜色。该组合物适用于光电转换元件的密封剂，例如蓝色LED或白色LED。（式中，R'各自独立地表示氢原子或甲基，m表示1至3的整数，n表示2至8的整数。）
