Description
特許文献1には、プリント回路板において使用する感光画像形成性カチオン重合性組成物であって、多官能性エポキシ樹脂であるビスフェノールAノボラック型エポキシ樹脂及び、可塑剤としての役割を果す反応性希釈剤の混合物と、カチオン性光開始剤とからなる組成物を開示しているが、耐熱性は高いものの柔軟性は十分であるといえない問題があった。
本発明における新規エポキシ樹脂は一般式(1)で示されるものであり、式中のE1は一般式(4)、又は一般式(5)を示し、E3は一般式(2)一般式(3)、一般式(6)、又は一般式(7)のいずれかを示し、E2は一般式(8)〜一般式(11)のいずれかを示すが、E2の少なくとも1つが一般式(9)である。
本発明のエポキシ樹脂硬化物は本発明のエポキシ樹脂組成物を光照射及びまたは加熱することによって得られる。
冷却管を設置したセパラブルフラスコにTD−EL(4,7−メタノ−2,3−エポキシオクタヒドロ−1H−インデン−オール 丸善石油化学株式会社製)164.5部とリカシッドMH−700(メチルヘキサヒドロフタル酸無水物、新日本理化株式会社製)160.2部とトルエン17.0部を仕込み、窒素ガス雰囲気下撹拌しながら加熱昇温した。この時水酸基に対する酸無水物基は0.951であった。130℃で反応を行い酸無水物が無くなるまで反応を行った。この反応により1分子中にエポキシ基を1個持ち、且つカルボキシル基を1個持つ化合物が得られた。続いてセロキサイド2021 300.8部、ZX−1658 374.4部を加えて加熱して均一とした。触媒としてTPP−BB(n−ブチルトリフェニルホスホニウムブロマイド、北興化学工業株式会社製)を0.1部アセトンに溶解して系内に加えた。130℃で反応を行い、酸価が無くなったことを確認して反応終点とした。得られたエポキシ樹脂のエポキシ当量は210.4g/eqだった。図1にGPCによる分子量分布を、図2にFTIRの測定結果を示す。
TD−ELを227.9部、リカシッドMH−700を222.2部、セロキサイド2021を200.7部、ZX−1658を349.1部とし、トルエンは使用しなかった。それ以外は実施例1と同様な操作を行った。水酸基に対する酸無水物基は0.952であった。得られたエポキシ樹脂のエポキシ当量は272.1g/eqだった。

ペンタエリスリトールを48.9部、リカシッドMH−700を138.3部、HBPA−DGEを403.1部、セロキサイド2021を403.1部とした以外は実施例1と同様な操作を行った。この時水酸基に対する酸無水物基は0.572であった。得られたエポキシ樹脂のエポキシ当量は273.5g/eqだった。
