インクの調製例1で使用した色素化合物(1a−1)を、下記比較用色素化合物(9)〜(12)に変更した。これ以外は、インクの調整例1と同様の操作をおこなって、比較用インク(H)〜(K)を調製した。
前記インクの調製例1〜7で得たインク(A)〜(G)、前記比較用インクの調製例1〜4で得た比較用インク(H)〜(K)をそれぞれ、キヤノン(株)製インクジェットプリンタPixus iP8600インクカートリッジに充填した。そして、前記インクジェットプリンタにて、キヤノン(株)製写真光沢紙プロフェッショナルフォトペーパー(PR−101)に2cm四方のベタ画像を印字させて記録物を作成した。得られた記録物を24時間自然乾燥して、評価用の記録物とした。
得られた記録物をアトラスウエザオメータ(Ci4000、(株)東洋精機製作所製)に投入し、50時間曝露した。このときの測定条件は、Black Panel:50℃、Chamber:40℃、Rel. Humidity:70%、Irradiance(340nm):0.39W/m2とした。照射前後の試験紙はSpectroLino(Gretag Machbeth社製)にて分析した。L*a*b*表色系における光学濃度及び色度(L*、a*、b*)を測定した。色差(ΔE)は色特性の測定値に基づき、下記式によって算出した。
色差(ΔE)=√{(a*試験前−a*試験後)2+(b*試験前−b*試験後)2+(c*試験前−c*試験後)2}
評価は以下の基準でおこなった。
◎:ΔEが5未満
○:ΔEが5以上、10未満
×:ΔEが10以上
得られた記録物をオゾンウェザーメーター(OMS−H、スガ試験機(株)製)にて、オゾン濃度10ppm、温度24℃、相対湿度60%の雰囲気下で記録物を4時間曝露した。そして、記録物の反射濃度を試験前後で測定した。得られた結果は耐光性の場合と同様の基準で判断した。色差(ΔE)は色特性の測定値に基づき、下記式によって算出した。
色差(ΔE)=√{(a*試験前−a*試験後)2+(b*試験前−b*試験後)2+(c*試験前−c*試験後)2}
◎:ΔEが5未満
○:ΔEが5以上、10未満
×:ΔEが10以上
前記インクの調製例1〜7で得たインク(A)〜(G)、前記比較用インクの調製例1〜4で得た比較用インク(H)〜(K)をそれぞれ、ガラス製の密閉容器に入れ、60℃、1ヶ月間静止放置した。その後、UV/Vis分光分析により最大吸収波長における吸光度(Abs)を測定し、60℃、1ヶ月間静止放置前における値(Abs0)と比較した。
評価は以下の基準でおこなった。
◎:Abs/Abs0が0.95以上
○:Abs/Abs0が0.90以上、0.95未満
×:Abs/Abs0が0.90未満
