Description
(a)第1の樹脂および溶媒を含む第1のエマルションの転相乳化(PIE)によってラテックスを製造し、アモルファス樹脂のTgより高い温度、結晶性樹脂の融点より高い温度、または前記第1のエマルションに含まれるときは両者の温度にさらされた前記第1のエマルションを用い、溶媒が蒸留されることと;
(b)ラテックスと、ワックスおよびマゼンタ着色剤とを合わせ、第2のエマルションを作成することと;
(c)前記第2のエマルションに凝集剤を加え、凝集した粒子を作成することと;
(d)前記凝集した粒子を融着させ、前記マゼンタトナーを作成することとを含み、
前記マゼンタトナーは、アモルファス樹脂のTgより低い温度、結晶性樹脂の融点より低い温度、またはコントロール樹脂に含まれるときは両者の溶媒蒸留温度で作られた前記コントロール樹脂を含む、同様に作られたコントロールマゼンタトナーと比較した場合、高収率、高スループットで、短い時間で、またはこれらの組み合わせで製造される、商業的な量でマゼンタトナーを製造する方法が開示される。
LMWアモルファスポリエステル樹脂およびHMWアモルファスポリエステル樹脂を使用し、転相乳化(PIE)を用いてラテックスを製造する。ポリエステル樹脂を、MEKおよびIPA、DIW(I)およびアンモニア(I)の混合物に溶解する。アンモニア(I)を使用してポリエステルを中和し、有機溶媒とDIW(I)の混合物への樹脂の分散を促進する。次いで、この均質な樹脂溶液にアンモニア(II)を加え、その後、DIW(II)を添加し、転相によって、水連続相中のポリエステル粒子の均一な懸濁物を作成する。この2種類のエマルションの配合物を表1および表2に提示する。
実施例1のラテックスを、2つの蒸留装置に分割した。片方の蒸留装置は、従来の58℃に設定された加熱ジャケットを備えており、他方は、65℃に設定されたジャケットを有しており、この温度は、HMW樹脂およびLMW樹脂のTgより高い。揮発性有機化合物(VOC)の含有量が、ガスクロマトグラフィー(GC)によって決定される場合、約300ppmを下回るまで蒸留を続けた。次いで、蒸留したラテックスを凍結乾燥し、特性決定した。表3は、58℃および65℃で蒸留したラテックスの特性を列挙している。
マゼンタトナーは、他の色と比較して、収率が悪く、幾何粒度分布(GSD)が非常に広く(粗粒子および微粒子の両方)、製造するのが最も困難なトナーである。問題は、赤色着色剤と関係があるだろう。
収率の上昇と同等に、このプロセスが、標準的なプロセスと少なくとも同等か、またはもっと高いスループットをもたらさない場合には、効率的で経済的な生産とは逆効果であろう。データから、従来の製造された樹脂を用いて作られたマゼンタトナー、または他の色のトナーの600kg/時間未満の1ヶ月の平均値と比較して、この1ヶ月で最も高いスループット(800kg/時間)は、熱処理したラテックスを用いたマゼンタトナーで得られたことがわかった。製造設備において、湿度が高いときに、夏の1ヶ月中の製造量が、ポリエステル粒子を乾燥させる能力を下げるとわかることは、予測できない(ポリエステルが水に高い親和性を有することに起因する)。予想できないことに、さらなる環境に関する課題と同等に、熱処理したラテックスを用いて最も高いスループットが得られ、驚くべきことに、マゼンタトナーのロットで起こった。
