Applications include molding materials, film-forming materials, solder masks in the production of printed (wiring circuit) substrates, plating resists, adhesives, lenses, displays, optical fibers, optical waveguides, holograms, coatings, and the like.
近年、活性エネルギー線で硬化し、高耐熱かつ高屈折率であって、透明性を有する感光性材料の開発が様々な用途で進められている(特許文献1〜3)。これらの用途では、高耐熱性、高屈折率以外にも基材への密着性や硬化物の硬度、アルカリに対する溶解性等が求められており、これらの要求に答えるためモノマーやフィラー等の添加剤を加えることが多い。しかしながら、これら添加剤を加えることで屈折率の低下等有機材料の特性を発現しにくくなるため、樹脂自体の耐熱性や屈折率の向上が必要となる。 In recent years, development of photosensitive materials that are cured with active energy rays, have high heat resistance and high refractive index, and have transparency has been promoted in various applications (Patent Documents 1 to 3). In these applications, in addition to high heat resistance and high refractive index, adhesion to the substrate, hardness of the cured product, solubility in alkali, etc. are required. To meet these requirements, addition of monomers and fillers is required. Additives are often added. However, the addition of these additives makes it difficult to exhibit the characteristics of the organic material such as a decrease in the refractive index, so that it is necessary to improve the heat resistance and refractive index of the resin itself.
特許文献4ではo−フェニルフェノールグリシジルエーテルと(メタ)アクリル酸(アクリル酸またはメタクリル酸)の反応物を光学材料として使用することが開示されている。しかし、この手法で得られた化合物は単官能の(メタ)アクリレートであり、硬化物における硬度・耐熱性が低いおそれがあり、また、液屈折率が1.58程度であることから、化合物としてはまだ満足のいくレベルではない。 Patent Document 4 discloses that a reaction product of o-phenylphenol glycidyl ether and (meth) acrylic acid (acrylic acid or methacrylic acid) is used as an optical material.

However, this compound is a monofunctional (meth) acrylate, and the hardness and heat resistance of the cured product may be low, and the liquid refractive index is about 1.57. is not.
さらに、近年、ハードネス、耐擦傷性並びに密着性が高く、高屈折率であり、高硬度で低収縮なカールの発生が少ないハードコート材料として、感光性のアクリル系ハードコート剤が利用されるようになってきており、特許文献7は加工処理スピード、ハードネス、耐擦傷性、連続加工、反射防止、帯電防止など、様々な機能を付与したハードコートについて述べている。 Furthermore, in recent years, photosensitive acrylic hard coat agents have been used as hard coat materials that have high hardness, scratch resistance and adhesion, a high refractive index, high hardness, and low shrinkage curl. Patent Document 7 describes a hard coat imparted with various functions such as processing speed, hardness, scratch resistance, continuous processing, antireflection, and antistatic.

以上の結果から、本発明の化合物(A)は従来の樹脂(H−1)、(H−2)、(I)よりも高屈折率であり、透明性を有し、フレネルレンズ、レンチキュラーレンズ、プリズムレンズ、マイクロレンズ等の各種レンズ、光ファイバーのコア材、クラッド材、光導波路、光配線、ホログラム、ディスプレー部材等の各種光学材料等の光学用途に有用である。 From the above results, the compound (A) of the present invention has a higher refractive index than the conventional resins (H-1), (H-2) and (I), has transparency, a Fresnel lens, and a lenticular lens. It is useful for optical applications such as various lenses such as prism lenses and micro lenses, optical fiber core materials, clad materials, optical waveguides, optical wirings, holograms, and display members.
