<p>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.</p> |
