Description
実施例1では、無水クロム酸をイオン交換水に溶解し、クロム濃度0.6g/Lのクロム酸溶液を作製し、苛性ソーダを用いてpHを5.7としたクロメート処理溶液を調製した。クロメート処理を施す銅箔には、8μm厚さの未処理電解銅箔(DFF:三井金属鉱業(株)製)を用い、硫酸100g/L水溶液に30秒間浸漬して酸洗いし、その後、イオン交換水に30秒間浸漬して水洗した。クロメート処理では、ガラスビーカー内のクロメート処理溶液の液温を40℃として緩やかに撹拌し、銅箔を3秒間浸漬後液切りし、温度70℃の加熱空気で3秒間乾燥し、クロメート処理銅箔を作製した。上述した試験条件を、以下に記載する実施例2〜9と比較例1〜5及び参考例の試験条件と併せて後の表1に示す。
実施例1で作製したクロメート処理銅箔は、恒温恒湿処理(50℃95%RHに設定した恒温恒湿槽で48時間保持)前後におけるドラム面幅方向の光沢度Gs(60°)を光沢度計(VG−2000:日本電色工業(株)製)で測定し、色調L*/a*/b*を色差計(SE−2000:日本電色工業(株)製)で測定し、耐変色性を評価した。評価結果を、以下に記載する実施例2〜9と比較例1〜5及び参考例の評価結果と併せて後の表2に示す。
比較例1では、実施例1で調製したクロメート処理溶液のpHを7.2とした以外は、実施例1と同様にしてクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
比較例2では、クロム濃度を3.6g/Lとし、pHが6.5になるよう調製したクロメート処理溶液に硫酸を添加してpHを3.2とした以外は、実施例1と同様にしてクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
比較例3では、クロム濃度を3.6g/Lとし、pHを12.5に調整したクロメート処理溶液を用いた以外は、実施例1と同様にしてクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
比較例4では、特許文献1の実施例1をトレースしたクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
比較例5では、後に示す参考例で調製したクロメート処理溶液を用いて複数枚の銅箔にクロメート処理を施し、pHが3.0になった段階で硫酸を添加してpHを1.3に再調整したクロメート処理溶液を用いた以外は、実施例1と同様にしてクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
参考例では、クロム濃度が3.6g/LでpHが1.3のクロメート処理溶液を用いた以外は、実施例1と同様にしてクロメート処理銅箔を作製し、耐変色性を評価した。評価結果を後の表2に示す。
ΔGs(光沢度差): 実施例1〜6と比較例1〜5とを対比すると、実施例のクロメート処理銅箔におけるΔGs(光沢度差)の値は0.3〜4.6であり、比較例の21.6〜67.1と対比すると、1/10のレベルである。なお、実施例1〜6は、浸漬クロメート処理した銅箔であるが、ΔGs(光沢度差)の値が、電解クロメート処理した銅箔である実施例7〜9とほぼ同レベルで良好である。
参考例で作製したクロメート処理銅箔では、ΔGs(光沢度差)の値が0.6、色差の値が1.79であり、実施例で作製したクロメート処理銅箔と同等レベルの耐変色性を備えている。これに対し、比較例5で作製したクロメート処理銅箔では、ΔGs(光沢度差)の値が52.7、色差の値が15.4であり、明らかに耐変色性に劣るクロメート処理銅箔となっている。
