摘要： The present invention discloses a monoepoxy compound represented by the following Formula (1), a curable composition containing the same, a cured product therefrom, a method of producing the monoepoxy compound, and a reactive diluent containing the monoepoxy compound. The monoepoxy compound represented by the Formula (1) is useful in that it is capable of reducing the viscosity of a curable composition containing the monoepoxy compound, while preventing a reduction in the heat resistance of the curable composition as well as a reduction in the weight of the curable composition upon curing. (In the Formula (1), R1 to R6 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, and an alkoxy group.)

摘要： An antifogging member has an concave-convex surface defined by convex portions and concave portions, a Fourier-transformed image obtained by applying two-dimensional fast-Fourier transform processing to an observation image of the concave-convex surface exhibits a circular or annular pattern having an origin for which the absolute value of the wave number is 0 μm−1 as the substantial center thereof, the convex portions and the concave portions extend in random directions in plan view, the average pitch of the concave portions and convex portions of the concave-convex surface is in the range of 50-250 nm, and the water contact angle on a smooth surface formed from the material constituting the concave-convex surface is 90 degrees or less. The antifogging member has high abrasion resistance, minimal haze, and a small difference in chromaticity and transmittance when viewed from oblique and perpendicular directions, and the transmittance and chromaticity thereof are not azimuth dependent.

摘要： The present invention discloses a curable composition comprising: an epoxy compound represented by the following Formula (1); and one selected from the group consisting of: a thermal cationic polymerization initiator, an acid anhydride-based curing agent and a curing accelerator, and a photo-cationic polymerization initiator as well as the cured product therefrom. The above described curable composition is useful in that it allows for the production of a cured product having a high heat resistance. (In the Formula (1), A represents CR17R18; B represents CR19R20; R1 to R20 each independently represents a substituent selected from the group consisting of a hydrogen atom, an alkyl group and an alkoxy group; and n represents 0 or 1, with the proviso that when n is 0, m represents 1, and when n is 1, m represents 0.)
