Problems solved by technology

[0003] However, for the epoxy acrylate derived from oxiranylbenzene, the role of 2-hydroxy-2-phenylethyl acrylate, which is the only public example, is exclusively a reactive diluent and a crosslinking agent, and has not focused on the use of resins. Improvement of epoxy acrylate itself for the purpose of improving physical properties

Embodiment 1

[0063] Put 8.10g (50mmol) of dioxirane (metasite / parasite=7 / 3) 8.10g (50mmol), acrylic acid 18.01g ( 250mmol), 0.23g (1mmol) of benzyltriethylammonium chloride, 0.055g (0.25mmol) of dibutylhydroxytoluene, and 100ml of toluene were heated and stirred at 80°C while introducing air, and allowed to react for 24 hours. After the reaction, it was cooled to room temperature, and washed three times with 100 ml of distilled water. The toluene layer was separated, and the toluene was distilled off, followed by purification with a silica gel column using ethyl acetate+hexane (4:6) as a developing solution. 9.34 g (yield 61%) of diepoxyacrylate benzene as a colorless and transparent viscous liquid was obtained. Determination of Diepoxyacrylate Benzene 1 H-NMR, 13 C-NMR spectrum. 13 The result of C-NMR measurement was α-adduct: β-adduct=5:1. Will 13 The C-NMR spectrum is shown in figure 1 .

Embodiment 2

[0069] 100 parts by weight of diepoxy acrylate benzene in Example 1 and 5 parts by weight of Ilgakyua 184 (manufactured by Ciba Specialty Chemicals Co., Ltd.; trade name) as a polymerization initiator were kneaded to prepare a composition. Apply it on a glass plate and an aluminum plate, cover with a release PET film, and use a high-pressure mercury lamp to irradiate energy to 600mJ / cm 2 Ultraviolet irradiation is carried out in a manner to cure it to obtain a film-like cured product.

Abstract

The disclosed epoxy acrylate, acrylic composition, and cured substance are highly heat-resistant, exhibit little thermal expansion, and are useful in a solder resist resin, an electroless plating resin, a hard-coat material, a UV-curable coating, a glass-replacement material, a liquid-crystal color filter, or the like. The disclosed epoxy acrylate, which is represented by general formula (1), can be obtained by reacting a diepoxy phenyl compound with either acrylic acid or methacrylic acid. The disclosed composition contains said epoxy acrylate and a polymerization initiator. In the formula, Z represents a C1-6 alkyl group and a represents a number from 0 to 4.

Description

technical field [0001] The present invention relates to a novel epoxy acrylate excellent in heat resistance, fluidity, toughness, photosensitivity, chemical resistance, and hardness, an acrylic composition, a cured product, and a production method thereof. This epoxy acrylate can be polymerized by itself or copolymerized with compounds having various unsaturated bonds to provide high-molecular materials with excellent heat resistance, toughness, chemical resistance, hardness, etc., and can be used in coatings. , laminated boards, adhesives and other applications. In addition, by making a photocurable resin composition or a thermosetting resin composition, it can also be used preferably as a resin for solder resist or a resin for electroless plating resist, a hard coat material, a UV curable paint, a glass substitute material, and protective films such as liquid crystal color filters. Background technique [0002] Epoxy acrylate resins, which are obtained mainly by the reac...
