The present invention provides a high-purity alicyclic epoxy compound in which an alicyclic olefin compound is epoxidized with an aliphatic percarboxylic acid having substantially no water followed by the removal of a solvent to produce an alicyclic epoxy compound represented by the general formula (I) that is in turn subjected to purification by distillation to thereby the high-purity alicyclic epoxy compound wherein the concentration of high-molecular-weight components having an elution time shorter than that of the alicyclic epoxy compound in detection by a GPC analysis is 5.5% or less in terms of the area ratio, the concentration of impurities having a retention time shorter than that of the alicyclic epoxy compound in detection by a GC analysis is 19.5% or less in terms of the area ratio, the concentration of reactive intermediates is 4.5% or less in terms of the area ratio, and a color hue (APHA) is 60 or less; a process of efficiently producing the same by the use of a low-toxicity solvent; a curable resin composition using the same; a cured product; and applications.

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.
