温度計、攪拌機、滴下ロート、及び還流冷却器を備えたフラスコに、メチルメタクリレートとメタアクリル酸を0.87:0.13のモル比で仕込み、溶媒としてジプロピレングリコールモノメチルエーテル、触媒としてアゾビスイソブチロニトリルを入れ、窒素雰囲気下、80℃で6時間攪拌し、カルボキシル基含有樹脂溶液を得た。この樹脂は、重量平均分子量が約10,000、酸価が74mgKOH/gであった。なお、得られた共重合樹脂の重量平均分子量の測定は、(株)島津製作所製ポンプLC−6ADと昭和電工(株)製カラムShodex(登録商標)KF−804,KF−803,KF−802を三本つないだ高速液体クロマトグラフィーにより測定した。以下、このカルボキシル基含有樹脂溶液を、A−1ワニスと称す。
温度計、攪拌機、滴下ロート、及び還流冷却器を備えたフラスコに、メチルメタクリレートとメタクリル酸の仕込み比をモル比で0.76:0.24とし、溶媒としてジプロピレングリコールモノメチルエーテル、触媒としてアゾビスイソブチロニトリルを入れ、窒素雰囲気下、80℃で6時間攪拌し、カルボキシル基含有樹脂溶液を得た。このカルボキシル基含有樹脂溶液を冷却し、重合禁止剤としてメチルハイドロキノン、触媒としてテトラブチルホスホニウムブロミドを用い、グリシジルメタクリレートを、95〜105℃で16時間の条件で、上記樹脂のカルボキシル基1モルに対し0.12モルの割合の付加モル比で付加反応させ、冷却後取り出した。上記反応により生成したカルボキシル基含有感光性樹脂の重量平均分子量は約10,000、酸価は59mgKOH/g、二重結合当量は950であった。以下、このカルボキシル基含有感光性樹脂溶液を、A−2ワニスと称す。
ソーダライムガラスに乾燥膜厚5μmおよび10μmの塗膜を形成した評価基板の吸光度を、紫外可視分光光度計を用いて測定した。得られたデータから、405nmにおける厚さ1μmあたりの吸光度を算出した。
L/S=50/200μmのラインを積算光量50mJ/cm2にて露光し、液温30℃の0.4質量%Na2CO3水溶液を用いて20秒間現像を行い、光学顕微鏡にてラインが形成できたかどうかを評価した。評価基準は以下の通りである。
積算光量を変えて露光を行い、L/S=50/200μmのラインが欠損無く形成できる最小の露光量を測定した。なお、比較例はレーザーでの露光時間が長くなり実用的ではないので、以後の試験は実施しなかった。
前記の最低露光量にて露光した場合の、アルカリ現像型の銀ペースト組成物における現像後のパターンを顕微鏡で観測し、ラインに不規則なばらつきがなく、よれ等がないかどうかで評価した。評価基準は以下のとおりである。
焼成後のライン形状は、焼成まで終了したパターンを顕微鏡で観測し、ラインに不規則なばらつきがなく、よれ等がないかどうかで評価した。評価基準は以下のとおりである。
密着性は、セロハン粘着テープによるピーリングを行い、パターンの剥離がないかどうかで評価した。評価基準は以下のとおりである。
パターン寸法0.4cm×10cmのCADデータをもちいて露光すること以外は、上記(焼成後のライン形状)の評価と同様にして試験基板を作製した。こうして得られた試験基板について、ミリオームハイテスターを用いて焼成皮膜の抵抗値を測定し、次いで、サーフコーターを用いて焼成皮膜の膜厚を測定し、焼成皮膜の比抵抗値を算出した。
