[0307] (1) Preparation of materials used in the cured resin composition

[0308] First prepare the following materials.

[0309]

[0310] 【chemical 19】

[0311]

[0312] Aa-1 above: Shin-Nakamura Chemical Co., Ltd. product name A-DCP

[0313] Aa-2 above: Trade name LIGHT-ACRYLATE BP-4EA manufactured by Kyoeisha Chemical Co., Ltd.

[0314] Aa-3 above: Trade name LIGHT-ACRYLATE BP-10EA manufactured by Kyoeisha Chemical Co., Ltd.

[0315] The above-mentioned Aa-4: synthesized by the following method.

[0316] The following reactions were carried out under nitrogen flow. 80.0 g of 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene and 40.5 g of triethylamine were dissolved in 1000.0 g of tetrahydrofuran. The reaction solution was ice-cooled and kept below 10°C, and 36.2 g of acryloyl chloride was added dropwise. After returning to room temperature, it was stirred for 2 hours. After adding an aqueous sodium bicarbonate solution to the reaction solution, extraction was performed...

Abstract

A curable resin composition containing a (meth)acrylate monomer having an aromatic ring, a non-conjugated vinylidene group-containing compound represented by general formula (1), and / or a thermal radical polymerization initiator and / or photo-radical polymerization initiator (where the non-conjugated vinylidene group-containing compound does not include the (meth)acrylate monomer) (R11, R12, R15, and R16 each independently represent a substituent group, and A represents an atomic group needed in order to form a cyclic structure) makes it possible to produce a cured product having minimized occurrence of burring during molding, high favorable product yield rate after molding, favorable heat coloration resistance, and low Abbe number.

Description

technical field [0001] The present invention relates to a semi-cured product, a cured product, a method for producing them, an optical component, and a cured resin composition. Background technique [0002] The camera module is used in a camera, a video camera or a camera phone, a TV phone, or a camera doorbell, etc. In recent years, miniaturization has been particularly demanded in the optical system used in the camera module. When downsizing an optical system, chromatic aberration of the optical system becomes a major problem. [0003] Conventionally, glass used as a material of an optical system can achieve various required optical properties and has excellent environmental resistance, but has a problem of poor processability. On the other hand, synthetic resins are lower in cost and excellent in processability than glass materials, but have a problem of being inferior to glass materials in heat resistance. [0004] There are known methods of adding various additives t...
