-
Paragraph 0148, (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.

Paragraph 0202; 0203; 0204; 0205, (2017/04/19)
An object of the present invention is to provide a curable epoxy resin composition, which is cured to provide a cured product having a high glass-transition temperature and particularly having excellent balance between heat resistance and transparency. The present invention relates to a curable epoxy resin composition comprising an alicyclic epoxy compound (A) represented by the following formula (1) and a curing agent (B), or a curable epoxy resin composition comprising an alicyclic epoxy compound (A) represented by the following formula (1) and a curing catalyst (C). [Formula 1] wherein R 1 to R 22 , which may be the same or different, each represent a hydrogen atom, a methyl group or an ethyl group; and m and n, which may be the same or different, each represent an integer of 1 to 4.
