Abstract
Description
のキナクリドンを、式:
の触媒である。
温度計、撹拌機及び凝縮器を備えた1リットル容のフラスコに、2,9−ジクロロ−6,13−ジヒドロキナクリドン45g、メタノール280ml及び45%水酸化カリウム水溶液136.8gを注入した。この混合物を、窒素の低速流の下に、還流温度で1時間撹拌して、2,9−ジクロロ−6,13−ジヒドロキナクリドン二カリウム塩を生成した。ナトリウム2,7−アントラキノン−ジスルホネート1.4gを加えた。次いで、16.9%過酸化水素水溶液67.6gを、窒素の低速流の下に、還流状態を維持しながら毎分0.3mlの速度で添加した。得られた青みを帯びた赤色の懸濁液を冷水100mlで希釈し、5分間撹拌して、ろ過した。プレスケークをメタノールで洗浄し、続いて熱水で洗浄したのち、乾燥させると、マゼンタ色の顔料が得られた。
ナトリウム2,7−アントラキノン−ジスルホネートの代りに他のアントラキノンスルホン酸誘導体を触媒として使用した以外は、上記手順を繰り返した。以下の表は、触媒の種類、その供給元を示し、例1〜5で得られる単離された2,9−ジクロロキナクリドンの純度を比較したものである。
温度計、撹拌機及び凝縮器を備えた1リットル容のフラスコに、6,13−ジヒドロキナクリドン50g、メタノール250ml、水36ml、結晶相配向剤かつ粒度縮小剤としてのフタルイミドメチルキナクリドン0.6g及び50%水酸化ナトリウム水溶液75gを注入した。この混合物を、窒素の低速流の下に、還流温度で1時間撹拌して、対応する6,13−ジヒドロキナクリドン二ナトリウム塩を生成した。2,7−アントラキノンジスルホン酸1.2gを添加し、得られた混合物を還流状態で10分間さらに撹拌した。その後、17%過酸化水素水溶液91.4gを、窒素の低速流の下に、還流温度を維持しながら毎分0.3mlの速度で添加した。得られた鮮やかな赤色の懸濁液を冷水100mlで希釈し、5分間撹拌したのち、50〜60℃でろ過した。プレスケークを熱水で洗浄したのち乾燥させると、HPLCによって分析した場合に触媒残渣100ppm未満を示す、高彩度な赤色のγ−キナクリドン顔料が得られた。
ポリ塩化ビニル63.0g、エポキシ化大豆油3.0g、バリウム/カドミウム熱安定化剤2.0g、フタル酸ジオクチル32.0g及び例6にしたがって調製したγキナクリドン1.0gを、ガラスビーカー中、撹拌棒を使用して混合した。この混合物を、実験室用2本ロール式圧延機で、160℃の温度、25rpmのローラ速度及び1:1.2の摩擦で8分間転動させ、一定に折り、取り出し、送ることにより、厚さ約0.4mmの軟質PVCシートに成形した。得られた軟質PVCシートは、魅力的な赤の色合いに着色され、熱、光及び移染に対する優れた堅ろう性を有するものであった。
例1にしたがって調製したマゼンタ2,9−ジクロロキナクリドン顔料5.0g、ヒンダードアミン光安定化剤2.5g、ベンゾトリアゾールUV吸収剤1.0g、ヒンダードフェノール酸化防止剤1.0g及びホスファイトプロセス安定化剤1.0gを、高密度ポリエチレン1000gとともに溶融後30秒間175〜200rpmの速度で混合した。溶融し、着色された樹脂を、暖かく展性であるうちに裁断したのち、造粒機に通した。得られた顆粒を、射出成形機で、5分のドエル時間及び30秒のサイクル時間で、260℃の温度で成形した。鮮やかなマゼンタ色を示し、優れた光安定性を有する均質に着色されたチップが得られた。
2,9−ジクロロキナクリドンの代りに例6にしたがって得られた赤色キナクリドン顔料を使用した以外は例8の手順を繰り返して、優れた光安定性を有する鮮やかな赤に着色されたチップを得た。
例1にしたがって調製した2,9−ジクロロキナクリドン顔料6.0g、ヒンダードアミン光安定化剤9.0g、ベンゾトリアゾールUV吸収剤3.0g及びヒンダードフェノール酸化防止剤3.0gをABS樹脂1200gとともに溶融後30秒間175〜200rpmの速度で混合した。溶融し、着色された樹脂を、暖かく展性であるうちに裁断したのち、造粒機に通した。得られた顆粒を、射出成形機で、7分のドエル時間及び42秒のサイクル時間で、232℃(華氏450度)及び288℃(華氏550度)の温度で成形した。各温度工程それぞれで同様なマゼンタの色合いを示す均質に着色されたチップが得られた。
ミルベース配合物
1パイント容のジャーにアクリル樹脂66g、AB分散剤14.5g及び溶媒(American ChemicalのSOLVESSO(登録商標)100)58.1gを注入した。例6にしたがって得られたキナクリドン顔料26.4g及び直径4mmの鋼ダイアゴナルロッド980gを添加した。この混合物を、ジャーの中、ローラミル上で64時間かけて磨砕した。このミルベースは顔料16.0%を含有し、顔料/バインダの比が0.5であり、全不揮発性成分含有率が48.0%であった。
上記ミルベース47.3g、メラミン樹脂触媒、非水分散樹脂及びUV吸収剤を含有する透明なソリッド着色剤溶液36.4g、ならびにポリエステルウレタン樹脂を含有するバランスの透明なソリッド着色剤溶液16.3gを混合し、キシレン76部、ブタノール21部及びメタノール3部を含有する溶媒混合物で、#2Fisher Cupによって計測して20〜22秒の吹付け粘度まで希釈した。
ポリプロピレン顆粒(Chemie LinzのDAPLEN PT-55(登録商標))1000g及び例1で得られた2,9−ジクロロキナクリドン顔料10gを混合ドラムの中で徹底的に混合した。このようにして得られた顆粒を260〜285℃で溶融紡糸して、優れた耐光堅ろう性及び紡織繊維性を有するマゼンタ色のフィラメントにした。
