-
Paragraph 0149-0150, (2018/05/26)
Provided is a photocurable composition which less causes resin-induced swelling of molds, allows the molds to endure more satisfactorily, and has excellent economic efficiency. This photocurable composition includes components (A), (B), (C), and (D). The component (A) is present in a content of 10 to 50 weight percent of the totality of photocurable compounds contained in the photocurable composition. The component (A) is a cycloaliphatic epoxy compound represented by Formula (a). The component (B) is an oxetane compound having a solubility parameter of 9.5 (cal/cm3)1/2 or more as determined by the Fedors' method. The component (C) is a glycidyl ether epoxy compound having a molecular weight of 250 or more. The component (D) is a photoinitiator: wherein R1 to R18 are each, identically or differently, selected from hydrogen, halogen, a hydrocarbon group optionally containing oxygen or halogen, and optionally substituted alkoxy; and X is selected from a single bond and a linkage group.

A high-purity cycloaliphatic diepoxy compound of General Formula (II) is an epoxidized product of a cycloaliphatic diolefinic compound of General Formula (I) having an isomer content as detected in gas chromatography (GC) of 15% or less: wherein X represents a bivalent group selected from the group consisting of, for example, O, S, -SO-, -SO2-, -CH2-, and -C(CH3)2-; and R1 to R18 may be the same as or different from each other and each represent hydrogen atom, a halogen atom, a hydrocarbon group which may contain oxygen atom or a halogen atom, or an alkoxy group which may be substituted. Such a high-purity cycloaliphatic diepoxy compound is prepared by producing the cycloaliphatic diolefinic compound through distillation, epoxidizing the compound with an aliphatic percarboxylic acid containing substantially no water, carrying out desolvation, and further purifying the epoxidized compound through distillation.

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.
