合成例1で得られた水酸基含有エポキシカルボキシレート化合物(D−1)含有の反応液335.5g、カルボキシル基を有するジオール化合物(E)としてジメチロールプロピオン酸54.9g、ジイソシアナート化合物(F)として2,4,4−トリメチルヘキサメチレンジイソシアナート104.1g、反応溶剤としてPGMEA85.6gを仕込み、反応温度80℃で反応させ、NCO含有量が0.1%以下となったところを反応の終点とし、ウレタン化合物(A−2)を得た。
合成例1で得られた水酸基含有エポキシカルボキシレート化合物(D−1)含有の反応液335.5g、カルボキシル基を有するジオール化合物(E)としてジメチロールブタン酸60.7g、ジイソシアナート化合物(F)としてイソホロンジイソシアナート100.1g、反応溶剤としてPGMEA87.1gを仕込み、反応温度80℃で反応させ、NCO含有量が0.1%以下となったところを反応の終点とし、ウレタン化合物(A−3)を得た。
攪拌装置、還流管をつけたフラスコ中に、1分子中に2個以上のエポキシ基を有するエポキシ樹脂である日本化薬製 RE−310S(エポキシ当量184g/eq.)を300.0g、一塩基酸(C)としてアクリル酸を117.5g、熱重合禁止剤として2,6−ジtert−ブチル−4−メチルフェノールを1.9g、反応触媒としてトリフェニルホスフィンを1.9g、反応溶媒としてPGMEA224.8gを仕込み、反応温度98℃にて反応液酸価が1mgKOH/g以下になるまで反応させ、水酸基含有エポキシカルボキシレート化合物(D−2)を得た。
攪拌装置、還流管をつけたフラスコ中に、1分子中に2個以上のエポキシ基を有するエポキシ樹脂である日本化薬製 RE−303S(エポキシ当量168g/eq.)を300.0g、一塩基酸(C)としてアクリル酸を128.7g、熱重合禁止剤として2,6−ジtert-ブチル−4−メチルフェノールを2.0g、反応触媒としてトリフェニルホスフィンを2.0g、反応溶媒としてPGMEA230.9gを仕込み、反応温度98℃にて反応液酸価が1mgKOH/g以下になるまで反応させ、水酸基含有エポキシカルボキシレート化合物(D−3)を得た。
合成例1〜3、比較合成例1〜2にて合成したそれぞれの感光性樹脂溶液に対して、日本化薬製 KAYARAD PEG400DAを140%、日本化薬製RE−306を40%、チバスペシャルティケミカルズ製イルガキュアー184(光重合開始剤)を3%混合し、樹脂物性評価用サンプルを作成した。その樹脂物性評価用サンプルを電解クロム酸処理鋼板上に膜厚約200μmで塗布後、600mJ/cm2の光量で照射し硬化させる。その後、硬化膜を基板上から取り出して150℃で1時間乾燥させた。なお、KAYARAD PEG400DAは光硬化性モノマー、RE−306はエポキシ樹脂である。
(Tgの測定方法)
上記方法で作製した硬化膜を幅5mmで切り出す。その後、Seiko instruments製粘弾性測定装置DMS6100にセットし、空気雰囲気中、周波数10Hz、昇温速度2℃/min.でtanδを測定し、tanδの最大値における温度をTgとした。
硬化膜を幅10mm、長さ120mmで切り出す。その後、オリエンテック製全自動引張り試験機テンシロンにセットし、20℃にて測定を行った。
厚さ25μmのポリイミドフィルム(東レデュポン製,カプトン100H)に、樹脂物性評価用サンプルを厚さ25μmで塗布し、600mJ/cm2の光量で照射し硬化させる。その後、ポリイミドフィルムと共に試験片として50mm×50mmに切り取り、150℃で1時間乾燥させて作製した試験片を得た。カット後、硬化皮膜層を上にして室温下に30分静置した後、試験片の4隅の水平面からのそり量を測定し、その平均値を反り量とした。
合成例1〜3、比較合成例1〜2で得られたそれぞれのウレタン化合物を用いて表2で示す配合割合にて混合し、3本ロールミルで混練後、感光性樹脂組成物を得た。これをスクリーン印刷法により乾燥膜厚が15〜25μmの厚さになるようにポリイミドフィルム(カプトン100EN、東レ・デュポン製)に塗布し、塗膜を80℃の熱風乾燥機で30分乾燥させた。次いで、紫外線露光装置((株)オーク製作所、型式HMW−680GW)を用い回路パターンの描画されたマスクまたは感度を見積もるためにコダック製ステップタブレットNo.2を通して500mJ/cm2の紫外線を照射した。その後、1%炭酸ナトリウム水溶液でスプレー現像を行って紫外線未照射部の樹脂を除去した。水洗乾燥した後、プリント基板を150℃の熱風乾燥器で60分加熱硬化し硬化膜を得た。
