1. 銀色の水性ベース塗料1の製造
表A中で「水相」に挙げられた成分を、記載された順序で水性混合物に撹拌混合する。次の段階で、「有機相」に挙げられた成分から有機混合物を製造する。この有機混合物を水性混合物に添加する。次いで、10分間撹拌し、脱イオン水及びジメタノールアミンを用いて8のpH値及び1000/secの剪断負荷で58mPasの吹付粘度(回転粘度計(Mettler-Teledo社の機器Rheomat RM 180)を用いて23℃で測定)に調節する。
本発明による水性ベース塗料E1を製造するために、水性ベース塗料1に市販の3,5,5−トリメチルヘキサノール1.5質量部を添加した。

表1中の質量パーセント表示は、その都度の水性ベース塗料中のアルコールの割合を基準とする。
ピンホール限界及びピンホール数の決定のために、多層塗装を次の一般的な手順で製造した:
被覆後に層厚差を算出できるように、プライマーサーフェーサー塗装が施された30×50cmの寸法の鋼板の縦方向の縁部に、接着テープを貼り付けた。この水性ベース塗料を、楔型に静電塗布した。この生じた水性塗料層を室温で1分間蒸発させ、引き続き空気循環炉中で70℃で10分間乾燥した。乾燥した水性塗料層上に、通常の二成分透明塗料を塗布した。この生じた透明塗料層を、室温で20分間蒸発させた。引き続き、この水性ベース塗料層及び透明塗料層を空気循環炉中で140℃で20分間硬化させた。生じた楔型の多層塗装中のピンホールの視覚的評価によって、ピンホール限界の層厚を決定した。この結果を表2中に示す。

この結果は、本発明によるアルコールの使用が、水性ベース塗料1と比較してピンホール限界を高め、かつ同時にピンホール数を低下させることを裏付ける。
