Embodiment 1

[0255] (Example 1) Curable composition (A-1)

[0256] Isopropanol-dispersed colloidal silica (silica content: 30% by mass, average particle diameter: 10 to 20 nm, trade name Snowtec IPA-ST; manufactured by Nissan Chemical Industry Co., Ltd.) 100 Parts by mass, add 6.0 parts by mass of γ-methacryloxypropyltrimethoxysilane and 9.0 parts by mass of phenyltrimethoxysilane to the detachable flask, stir and mix, and then add 0.1825% by mass of 4.8 parts by mass of the HCl solution was stirred at 20° C. for 24 hours to surface-treat the silica fine particles.

[0257] Disappearance by hydrolysis of γ-methacryloxypropyltrimethoxysilane and phenyltrimethoxysilane was confirmed by gas chromatography (Agilent Co., Ltd. model 6850). Use a non-polar column DB-1 (manufactured by J&W Co., Ltd.), set the temperature at 50 to 300°C, heat up at a rate of 10°C / min, use helium as a carrier gas, and set the flow rate at 1.2cc / min. The chemical detector was determined by the internal standard met...

Embodiment 2

[0260] (Example 2) Curable composition (A-2)

[0261] Except that the amount of DAND used in Example 1 is changed to 10 parts by mass, the amount of A-BPEF used is changed to 21 parts by mass, and the amount of EA-F5503 used is changed to 19 parts by mass, the same operation is carried out as in Example 1, and A curable composition (A-2) was obtained.

Embodiment 3

[0262] (Example 3) Curable composition (A-3)

[0263] Except that the amount of DAND used in Example 1 was changed to 11 parts by mass, the amount of A-BPEF used was changed to 21 parts by mass, and EA-F5503 was not used, a curable composition was obtained in the same manner as in Example 1. (A-3).

Abstract

The present invention provides a curable composition, wherein a cured material obtainable by curing the curable composition has excellent transparency, thermal durability and surface hardness and has a small Abbe number. In particular, the present invention provides a curable composition containing (a) silica fine particles; (b) a (meth)acrylate compound having two or more ethylenically unsaturated groups; (c) a (meth)allyl compound having two or more ethylenically unsaturated groups and having an aromatic ring structure; and (d) a polymerization initiator; wherein the surface of the silica fine particles (a) has been treated with a specified silane compound (e) and a specified silane compound (f).

Description

technical field [0001] The present invention relates to a specific curable composition and a cured product obtained by curing the composition, which is excellent in transparency, heat resistance, and surface hardness, and has a low Abbe number. Background technique [0002] In recent years, with the advancement of optical industry technologies such as optical devices, optical communications, and displays, materials with excellent optical properties have been desired. Examples of such materials include optical lenses, optical disc substrates, plastic substrates for liquid crystal display elements, substrates for color filters, plastic substrates for organic EL display elements, solar cell substrates, touch panels, optical elements, optical waveguides, and LED sealing materials. Wait. In particular, expectations for optical performance of optical lenses, optical elements, and optical waveguide materials are high. [0003] In general, inorganic glass is used in large quantiti...
