Description
室温にて固体状のエポキシ樹脂100重量部に対しそれぞれ、カルボン酸化合物1〜 10重量部、硬化反応開始温度150℃以上の硬化剤1〜30重量部、及び溶剤10 〜300重量部を含有する活性樹脂組成物。
本願の活性樹脂組成物には、室温にて固体状のエポキシ樹脂を含有する。エポキシ樹脂は、マトリックス樹脂としての機能を有する。また、エポキシ樹脂は、硬化反応時に後述の活性剤とも反応し、活性剤を失活させる機能を有する。これに拠り、硬化後の塗布樹脂層は、非常に熱的安定となり、加熱時(例えば、アンダーフィル樹脂の加熱硬化時)、腐食反応や分解ガスを発生することがない。エポキシ樹脂の軟化点としては、例えば70〜150(特に80〜100)℃が好ましい。具体的には、エポキシ樹脂としては、クレゾールノボラック型エポキシ樹脂、ジシクロペンタジエン系エポキシ樹脂、ビフェニル系エポキシ樹脂、ビスフェノールA型固形エポキシ樹脂、固形の脂環式エポキシ樹脂等が挙げられる。
・実施例1
先ず、下記組成の均一なペースト状活性樹脂組成物を調製した。
組成)クレゾールノボラック型エポキシ樹脂(軟化点94℃)100重量部、p−ヒドロキシ安息香酸4重量部、ジシアンジアミド5重量部、プロピレングリコールメチルエーテルアセテート50重量部。
