The invention I provides a method of producing an alicyclic epoxy compound having a specific structure, which comprises epoxidizing an alicyclic olefin compound having a specific structure by using an aliphatic percarboxylic acid having low water content. The alicyclic epoxy compound is useful for use in coatings, inks, adhesives, sealants, encapsulants, stabilizers or the like.
The invention II provides an epoxy resin composition containing the alicyclic epoxy compound as a main component, and a photosemiconductor device comprising a photosemiconductor element encapsulated with the epoxy resin composition. The epoxy resin composition can be cured by heating, thereby obtaining a cured product having excellent moisture and heat resistance and transparency.
The invention III provides: an ultraviolet rays-curable can-coating composition containing the alicyclic epoxy compound as a main component, which can be cured by ultraviolet irradiation, and can form a coating film having excellent film performances such as processability, adhesion, hardness and scratch resistance, particularly film appearance and retort resistance; and a process of producing a coated metal can using the composition.
本发明一提供了一种生产具有特定结构的脂环族环氧化合物的方法,该方法包括使用含水量低的脂肪族过羧酸对具有特定结构的脂环族烯烃化合物进行环氧化。脂环族环氧化合物可用于涂料、油墨、粘合剂、密封剂、封装剂、稳定剂等。
本发明二提供了一种含有脂环族环氧化合物作为主要成分的环氧树脂组合物,以及一种光电半导体器件,该器件包括用环氧树脂组合物封装的光电半导体元件。环氧树脂组合物可以通过加热固化,从而获得具有优异的耐湿性、耐热性和透明度的固化产品。
本发明III提供了:一种紫外线固化罐涂层组合物,该组合物以脂环族环氧化合物为主要成分,可通过紫外线照射固化,并可形成具有优异涂膜性能(如加工性、附着力、硬度和抗划伤性)的涂膜,特别是涂膜外观和耐蒸煮性;以及一种使用该组合物生产涂层金属罐的工艺。
