Description

【発明の属する技術分野】
本発明は、新規なビニル化合物に関し、さらに該化合物を含有する硬化性樹脂組成物ならびにそれらの硬化物に関する。本発明のビニル化合物は、それ自体を重合させることによってまたは他の不飽和化合物と共重合させることによって、耐熱性および誘電特性に優れた高分子材料を得ることができるものである。また、本発明のビニル化合物は、光重合開始剤と組み合わせることによって、感光性樹脂組成物とすることもでき、かかる感光性樹脂組成物は、レジスト用樹脂、液晶表示パネルの封止用樹脂、液晶のカラーフィルター用樹脂、UV塗料、各種コーティング剤、接着剤、ビルドアップ積層板材料等の広範な用途に用いることができる。
【0002】
【従来の技術】
従来、ビニル化合物は、感光材料、光学材料、歯科材料、電子材料、各種高分子の架橋剤など、種々の機能性高分子材料の原料として幅広く用いられている。しかしながら、近年これらの応用分野における要求性能の高度化に伴い、機能性高分子材料として求められる物性はますます厳しくなってきている。かかる物性として、例えば、耐熱性、耐候性、耐薬品性、低吸水性、高屈折率、高破壊靭性、低誘電率、低誘電正接等が求められているが、これまでのところ、これらの要求物性は必ずしも満足されてきたわけではない。
【0003】
【本発明が解決しようとする課題】
本発明は、熱および光で硬化でき、硬化物が優れた耐熱性を有し、低誘電率、低誘電正接である新規なビニル化合物および硬化性樹脂組成物を提供することにある。
【0004】
【課題を解決するための手段】
本発明者等は、PPEの優れた誘電特性・耐熱性を引継いだ2官能性PPEオリゴマーの末端に熱硬化性官能基を導入した化合物(特願2002−018508)、熱および光硬化性官能基を導入した化合物(特願2002−038156、特願2002−055765)を合成した。しかしながら、熱硬化性官能基を導入した化合物は、優れた低誘電特性を有するものの光硬化できず、一方、熱および光硬化性官能基を導入した化合物は、光硬化可能なものの熱硬化性化合物の低誘電特性には及んでいなかった。そこで、熱および光硬化性官能基を有し、熱硬化性化合物並の低誘電特性を有する化合物を得るために鋭意検討を重ねた結果、構造式(1)で示され、−(O−X−O)−が構造式(2)であり、−(Y−O)−が構造式(3)で定義される1種類の構造、または2種類以上の構造がランダムに配列した2官能PPEのオリゴマー体にビニル基を導入することで、硬化性が良好で低誘電率、低誘電正接、高耐熱の硬化物が得られることを見出し、本発明を完成するに至った。すなわち、本発明は、一般式(1)に表されるビニル化合物に関する。
