実施例のインクジェット記録用インク1~27及び比較例のインクジェット記録用インク1~7について下記評価を行った。その結果を表1に示した。
なお、表1において、各評価は、各インクジェット記録用インクをインクカートリッジに装填し、インクジェットプリンター(エプソン(株)製;PM-700C)で写真用紙(エプソン(株)製写真紙<光沢>)に画像を記録した後で評価したものである。
印画したサンプルを目視で観測し、純色のマゼンタである場合をA、やや赤みがかった赤色に近いマゼンタをB、明らかに赤紫色の場合をCの三段階で評価した。
印画物の彩度(C*)を、色特性に測定に基づき、下記式によって算出した。印加電圧50%における印画画像部分について、反射濃度計(商品名 X-Rite 310TR、Xrite社製)を用いて、CIE L*a*b*表色系(国際照明委員会規格(1976年)/又はJIS規格Z8781-4:2013)における明度L*と色度a*及びb*を測定し、得られた値から下記算出式に基づいて彩度(C*)を求め、評価を行い、下記判定基準により評価した。
B: C*が80以上90未満の場合
C: C*が80未満の場合
インクジェットプリンター(商品名PM-700C、セイコーエプソン株式会社製)及びインクジェットプリンター(キヤノン(株)製;PIXUS Pro9000MkII)を使用し、上記に示したインクジェット記録用インクを用いて、インクジェット専用記録媒体{写真用紙<光沢>(商品名、セイコーエプソン株式会社製)}及びインクジェット専用紙(キヤノン(株)製;フォト光沢紙PT-201)にマゼンタ(Magenta)色のOD(Optical Density)値が0.1~2.0の範囲で階段状に濃度が変化した単色の画像パターンを印字させた。写真用紙に印画濃度(ODmax)における反射濃度を画像濃度を反射濃度計(X-Rite310TR)を用いて測定し、印画濃度が2.00以上の場合をA、1.8以上2.0未満の場合をB、1.8未満の場合をC、1.7未満の場合をDとして、四段階で評価した。
記録した直後の画像濃度Ciを測定した後、ウェザーメーター(アトラスC.165)を用いて、画像にキセノン光(10万ルクス)を28日間照射した後、再び画像濃度Cf1を測定し、キセノン光照射前後の画像濃度から色素残存率を算出し評価した。画像濃度は反射濃度計(商品名 X-Rite 310TR、Xrite社製)を用いて測定した。色素残存率は、初期の画像濃度が1.0±0.2の画像部分を用いて測定した。
次式より色素残存率を求め、下記判定基準により評価した。
色素残存率(%)=(Cf1/Ci)×100
B: 色素残存率が80%以上90%未満の場合
C: 色素残存率が80%未満の場合
シーメンス型オゾナイザーの二重ガラス管内に乾燥空気を通しながら、5kV交流電圧を印加し、これを用いてオゾンガス濃度が5±0.1ppm、室温、暗所に設定されたボックス内に、画像を形成したフォト光沢紙を3日間放置し、オゾンガス下放置後の画像濃度を反射濃度計(商品名 X-Rite 310TR、Xrite社製)を用いて測定し、初期の画像濃度Ciとオゾンガス下放置後の画像濃度Cf2から色素残存率を算出し評価した。なお、色素残存率は、初期の画像濃度が1.0±0.2の画像部分を用いて測定した。ボックス内のオゾンガス濃度は、APPLICS製オゾンガスモニター(モデル:OZG-EM-01)を用いて設定した。
次式より色素残存率を求め、下記判定基準により評価した。
色素残存率(%)=(Cf2/Ci)×100
B: 色素残存率が80%以上85%未満の場合
C: 色素残存率が80%未満の場合
高湿条件下での画像のにじみについては、マゼンタの1mm×1mmの正方形を、正方形同士の間に0.5mmの白地隙間が形成されるように配置した、3cm×3cmの印字パターンを作製し、この画像サンプルを45℃相対湿度80%の条件下、7日間保存後に白地隙間におけるマゼンタ染料のにじみを観察した。
具体的には、上記高湿条件に晒す前と晒した後の印刷物のOD値を、反射濃度計(「Spectrilino」(商品名:Gretag社製)を用いて測定し、印字直後に対する白地のマゼンタ濃度増加がステータスAのグリーンフィルターにおいて、0.02未満の場合をA、0.02以上0.05未満の場合をB、0.05以上0.10未満の場合をC、0.10以上の場合をDとした。
吐出安定性については、本発明の実施例及び比較例で得られたインクジェット記録用インクをインクジェット記録装置(商品名:商品名PM-700C、セイコーエプソン株式会社製)用のインクカートリッジに充填し、該カートリッジを上記インクジェット記録装置にセットし全ノズルからのインクの吐出を確認した後、A4 100枚出力し、以下の基準で評価した。 更に、本発明の実施例及び比較例で得られたをインクジェット記録用インクを40℃80%RHの条件下2週間保存後に、再び上記実験を行い、インクジェット記録用インク調整直後のインク吐出性との差異が在るか否かを評価した。
強制保存試験前・後で、以下の基準で差異を評価した。
A:印刷開始から終了まで印字の乱れが殆ど無し
B:印字の乱れのある出力が発生する
C:印刷開始から終了まで終始印字の乱れあり
本出願は、2016年9月30日出願の日本特許出願(特願2016-193944)、2017年2月3日出願の日本特許出願(特願2017-19100)に基づくものであり、その内容はここに参照として取り込まれる。
