[6][5]に記載の接着体の製造方法であって、前記主剤及び前記開始剤を含む接着剤組成物を介して、前記第1の被着体と前記第2の被着体とを貼り合わせる工程を備える、接着体の製造方法。
一実施形態の接着剤セットは、脱錯化剤を含有する主剤と、有機ボラン錯体及びN,N-二置換(メタ)アクリルアミドを含有する開始剤とを備える。本実施形態の接着剤セットは、主剤及び開始剤を混合することによって、主剤及び開始剤を含む接着剤組成物を得ることができる。
開始剤は、有機ボラン錯体を含有する。有機ボラン錯体とは、有機ボランにルイス塩基を配位させて錯体化した、有機ボラン-ルイス塩基錯体を意味する。有機ボラン-ルイス塩基錯体は、後述の脱錯化剤と反応して、有機ボランを与える化合物である。有機ボランは、酸素存在下でラジカル開裂を生じ、ボリン酸ラジカル等が発生することから、リビングラジカル重合の開始剤として作用し得る。有機ボランは、例えば、アルキルボラン(BR3、R:アルキル基)であってよい。ルイス塩基は、例えば、アミンであってよい。アミンは、例えば、複数のアミノ基を有する化合物、又は、アミンを構成するアミノ基と、当該アミノ基の窒素原子以外に、ホウ素に配位可能な原子(例えば、酸素原子等)を含む基(例えば、アルコキシ基等)とを少なくとも有する化合物であってよい。これらの化合物は、有機ボランに対して多座型配位子として作用することから、多座型アミンということができる。
開始剤は、N,N-二置換(メタ)アクリルアミドを含有する。N,N-二置換(メタ)アクリルアミドは、有機ボラン錯体の安定化に作用し得るとともに、接着剤セットの安定化に寄与し得る安定化剤であり得る。ここで、N,N-二置換(メタ)アクリルアミドとは、(メタ)アクリルアミドの窒素原子上の2個の水素原子が水素原子以外の基に置換された化合物を意味する。N,N-二置換(メタ)アクリルアミドは、例えば、N,N-二置換アクリルアミドであってよい。
主剤は、脱錯化剤を含有する。脱錯化剤とは、有機ボラン錯体(有機ボラン-ルイス塩基錯体)中のルイス塩基を解離させて有機ボランを発生させることができる化合物である。そのため、開始剤に含有される有機ボラン錯体と主剤に含有される脱錯化剤とを混合して反応させることによって、リビングラジカル重合の開始剤となり得る有機ボランを発生させることができる。
主剤及び開始剤の少なくとも一方は、ラジカル重合性基を有する化合物をさらに含有する。ラジカル重合性基を有する化合物は、ラジカルによって反応する重合性基を有する化合物である。ラジカル重合性基としては、例えば、例えば、(メタ)アクリロイル基、ビニル基、アリル基、スチリル基、アルケニル基、アルケニレン基、マレイミド基等が挙げられる。
主剤及び開始剤の少なくとも一方は、重合制御剤としての、ハロゲン化金属塩及びチオカルボニルチオ構造を有する化合物からなる群より選ばれる少なくとも1種をさらに含有する。
フィラーは、例えば、無機フィラー又は有機フィラーのいずれかであってよい。無機フィラーとしては、例えば、シリカ、アルミナ、シリカ-アルミナ、チタニア、ジルコニア、マグネシア、カオリン、タルク、炭酸カルシウム、ベントナイト、マイカ、セリサイト、ガラスフレーク、ガラス繊維、黒鉛、水酸化マグネシウム、水酸化アルミニウム、三酸化アンチモン、硫酸バリウム、ホウ酸亜鉛、ウォラストナイト、ゾノトライト、ウィスカー等の無機微粒子などが挙げられる。フィラーとして無機フィラーを用いる場合、無機フィラーは、シリカフィラーを含んでいてもよい。
可塑剤としては、例えば、フタル酸エステル系化合物、アルキルスルホン酸エステル系化合物、アジピン酸エステル系化合物等が挙げられる。
一実施形態の接着体は、第1の被着体と、第2の被着体と、第1の被着体及び第2の被着体を互いに接着する接着剤層とを備える。接着剤層は、上記の接着剤セットにおける主剤及び開始剤を含む接着剤組成物の硬化物を含有する。
