本発明による硬化性樹脂組成物に含まれる金属錯体触媒(B)は、上記したシアン酸エステル化合物等の重合を触媒する機能を有するものである。金属錯体触媒(B)としては、従来公知のものを使用することができる。例えば、オクチル酸、ステアリン酸、アセチルアセトネート、ナフテン酸、サリチル酸等の有機酸のZn、Cu、Fe、Co、Mn、Al等の有機金属塩等が挙げられ、これらの中でもオクチル酸亜鉛、オクチル酸銅、オクチル酸コバルト、オクチル酸アルミニウム、ステアリン酸亜鉛、ステアリン酸銅、ステアリン酸コバルト、ステアリン酸アルミニウム、アセチルアセトン亜鉛、アセチルアセトン銅、アセチルアセトン鉄、アセチルアセトンマンガン、アセチルアセトンコバルト、アセチルアセトンアルミニウム、ナフテン酸亜鉛、ナフテン酸銅、ナフテン酸コバルト、ナフテン酸アルミニウムが好ましく、オクチル酸亜鉛、オクチル酸銅、オクチル酸コバルト、ステアリン酸亜鉛、ステアリン酸コバルト、アセチルアセトン亜鉛、アセチルアセトン銅、アセチルアセトンマンガン、アセチルアセトンコバルト、ナフテン酸亜鉛、ナフテン酸銅、ナフテン酸コバルト、ナフテン酸アルミニウムがより好ましい。これらの金属錯体触媒は1種または2種以上混合して用いることができる。金属錯体触媒(B)を添加することによって、硬化性樹脂組成物の硬化温度を下げることができる。
本発明による硬化性樹脂組成物は、下記一般式(II)で示される化合物、下記一般式(III)で示される化合物、および三級アミンからなる群より選択されるいずれか1種以上の添加剤(C)を含む。
本発明による硬化性樹脂組成物は、上記したシアン酸エステル化合物(A)に加えて、さらに他のシアン酸エステル化合物(D)を含んでいてもよい。このようなシアン酸エステル化合物(D)としては、下記一般式(IV)~(VI)で示される化合物を好適に使用することができる。
本発明による硬化性樹脂組成物は、上記したシアン酸エステル化合物(A)、金属錯体触媒(B)、および添加剤(C)、さらに必要に応じて、上記一般式(VI)、(VII)および(VIII)で表わされるシアン酸エステル化合物(D)、エポキシ樹脂(E)、マレイミド化合物(F)、ベンゾオキサジン化合物および/または重合可能な不飽和基を有する化合物や各種添加剤を、溶媒とともに、公知のミキサー、例えば高速ミキサー、ナウターミキサー、リボン型ブレンダー、ニーダー、インテンシブミキサー、万能ミキサー、ディゾルバー、スタティックミキサーなどを用いて混合して得ることができる。混合の際の、シアン酸エステル化合物、各種添加剤、溶媒の添加方法は、特に限定されるものではない。
本発明による硬化性樹脂組成物は、熱や光などによって硬化させることにより硬化物とすることができる。硬化物は、硬化性樹脂組成物を溶融または溶媒に溶解させた後、型内に流し込み、通常の条件で硬化させることにより得ることができる。熱硬化の場合、硬化温度は、低すぎると硬化が進まず、高すぎると硬化物の劣化が起こることから、120℃から300℃の範囲内が好ましい。
上記した硬化性樹脂組成物を、基材に含浸または塗布することにより、プリプレグを製造することができる。
