Description
非イオン性有機ポリマー粒子M1を用いた多孔質粒子の調製
有機相を、Kao Eバインダーの20重量%溶液96.2g及びヘプタン3.6gに溶解した0.18gのMlを用いて調製した。この有機相を、11gのNalcoTM2329を含有するpH4のクエン酸塩緩衝液139gと2.2gの10重量%促進剤溶液とを用いて調製した水性混合物と一緒に混合し、SilversonL4R Mixer(Silverson Machines,Inc.製)を用いる超高剪断にかけ、次いでMicrofluidics製のMicrofluidizer Model#110Tにかけた。回転蒸発器を用いて減圧下で有機溶媒を除去した。得られた粒子は平均粒径7.5μmを有していた。図1は、例1の粒子のSEM断面であり、粒子中の細孔を示している。
非イオン性有機ポリマー粒子M1を用いた顔料を含有する多孔質粒子の調製
12.71gのKaoバインダーE、1.688gのBASF Lupreton Blue SE 1163、50.0gの酢酸メチル、0.60gの非イオン性有機ポリマー粒子M1、及び10.0gのヘキサンを含む有機相を調製した。この有機相を、103.76gの水、0.689gのフタル酸水素カリウム、6.60gのNalco1060、及び1.452gの10%促進剤を含有する水性混合物と混合した。
12.71gのKaoバインダーE、1.688gのBASF Lupreton Blue SE 1163、60.0gの酢酸メチル、及び0.60gの非イオン性有機ポリマー粒子M1を含む有機相を調製した。水性相は例2の水性相と同じであった。有機相の水性相中で分散させ、そして例1と同様に溶媒を除去した。得られた5.9μmトナーを光学顕微鏡で分析すると、細孔を示さなかった。この結果は、非イオン性有機ポリマー粒子と関連する第二の炭化水素溶媒が、細孔生成には必要であることを示している。
12.68gのKaoバインダーE、1.688gのBASF Lupreton Blue SE 1163、30.0gの酢酸メチルを含む有機相を調製した。第二の有機相を、15.0gのヘキサン、15.0gの酢酸メチル、0.030のSPANTM65(Fluka製)、及び0.60gの非イオン性有機ポリマー粒子M1を用いて調製した。2つの有機相を一緒にし、その後例3の水性相と同じ水性相と混合した。例1と同様に均一化した後、この分散体を200gの水と200gの3Aアルコールとの混合物で処理した。その後、有機溶媒を回転蒸発器で、減圧下で除去した。固体トナー粒子を、焼結ガラスフィルターを通してろ過によって集めて、水で洗浄した。得られた5.9μmトナーを光学顕微鏡で分析すると、細孔を示した。
15.75gのKaoバインダーE、2.25gのBASF Lupreton Blue SE 1163、70.0gの酢酸メチル、10.0gのヘキサン、及び2.00gの非イオン性有機ポリマー粒子M2を含む有機相を調製した。この有機相を、138.35gの水、0.918gのフタル酸水素カリウム(KHP)、8.80gのNalcoTM1060及び1.936gの10%促進剤を用いて調製した水性相と一緒に混合した。この混合物を、その後、例1に記載したように超高剪断にかけた。マイクロフリューダイザーを出るときに、この混合物を3Aアルコールの50%水溶液に添加し、減圧下で回転蒸発にかけた。添加したアルコールの50%を除去した後、生じた懸濁物をろ過して、トナー粒子を脱イオン水で洗浄し、その後、32℃で20時間真空オーブン中で乾燥させた。得られた粒子は、7.2μmの平均粒径を有していた。破砕したトナー粒子のSEM画像である図3から明らかなようにこの粒子は細孔を有することを示した。
