実施例で合成したフタロシアニン化合物0.3質量部をロジン変性フェノール樹脂使用ワニス2.0質量部に分散した。得られた着色組成物を白色紙上に展色し、分光光度計(GetragMacbeth社製SpectroEye)を用いて色特性を測定した。得られた結果を表1に示す。
(光源D65、2度視野)
表1中、C*は彩度を表し、hは色相角を表す。各々合成した化合物は緑色の色相を有した。
実施例3で得られたフタロシアニン化合物(29)0.50質量部を塩化ナトリウム1.50質量部、ジエチレングリコール0.75質量部とともに磨砕した。その後、この混合物を600質量部の温水に投じ、1時間攪拌した。水不溶分を濾過分離して温水でよく洗浄した後、80℃で減圧下乾燥し、顔料化を行った。顔料の粒子径は、300nm以下、粒子の平均長さ/幅比は3未満であった。
得られたフタロシアニン化合物(29)の緑色顔料を用いて、下記の焼付塗膜展色試験および耐薬品性試験を行った。
