Description
所望の平均粒子径及び該所望の粒子径のばらつきの少なくとも一方を選択することと、
転相により硬化性ポリエステルを含むエマルジョンを形成することと、
前記転相における、溶媒比、中和率、及び温度を、下記伝達関数に従って制御することと、を含む方法:
Y=Z1×{575−[(447.4)(SR)]−[(163.75)(NR)]+[(0.3285)(T)(SR)]};及び
S=Z2×{789−[(2.87)(T)]+[(256.9)(SR)]−[(586.4)(NR)]+[(2.27)(T)(NR)]−[(250.8)(SR)(NR)]};
ここで、Yは前記所望の平均粒子径(nm)を表し、Sは、前記所望の粒子径のばらつき(nm)を表し、SRは総固形分に対する溶媒比(重量)を表し、NRは中和率を表し、Tは温度(K)を表し、Z1及びZ2は独立して、0.8〜1.2である誤差因子を表す。
(1)Y=575−[(447.4)(SR)]−[(163.75)(NR)]+[(0.3285)(T)(SR)];及び
(2)S=789−[(2.87)(T)]+[(256.9)(SR)]−[(586.4)(NR)]+[(2.27)(T)(NR)]−[(250.8)(SR)(NR)]、
ここで、Yはエマルジョンの平均粒子径(ナノメートル)を表し、Sは同一の条件セットに対するエマルジョンの粒子径のばらつき(ナノメートル)を表し、SRは樹脂に対する溶媒比(重量比)を表し、NRは中和率(樹脂に対する塩基の比)を表し、Tはケルビン単位(セ氏単位の温度プラス273と定義される)での温度を表す。本明細書において、溶媒比とは、総固形分(樹脂及び開始剤)に対する溶媒の重量比を指す。
(1)Y=Z1×{575−[(447.4)(SR)]−[(163.75)(NR)]+[(0.3285)(T)(SR)]};及び
(2)S=Z2×{789−[(2.87)(T)]+[(256.9)(SR)]−[(586.4)(NR)]+[(2.27)(T)(NR)]−[(250.8)(SR)(NR)]}、
ここで、Z1及びZ2はそれぞれ、例えば、約0.8〜約1.2、約0.9〜約1.1、又は約0.95〜約1.05の誤差因子(error factor)を表す。従って、これらの誤差因子は、伝達関数によって所定のばらつきの範囲内にある所望のエマルジョン粒子径予測が可能になる一方で、厳密な数学的正確性は、程度は小さいものの、その他のプロセス変動要素(process variables)に影響されるということを考慮したものである。
Y=184.97nm=575−[(447.4)(0.618)]−[(163.75)(1.10)]+[(0.3285)(328)(0.618)];及び
S=9.386nm=789−[(2.87)(328)]+[(256.9)(0.618)]−[(586.4)(1.10)]+[(2.27)(328)(1.10)]−[(250.8)(0.618)(1.10)]
であると予測される。
本明細書において、所望の平均粒子径のばらつきとは、所望の平均粒子径の標準偏差を指す。標準偏差の範囲は、約1〜約20nmであり、約5〜約15nmであることが好ましく、約8.45〜約10.32nmであることがさらに好ましい。
本明細書で開示する転相法では、まず、樹脂及びその他の成分を、通常は水と混和しない有機溶媒中へ溶解することを行なう。樹脂に対する溶媒の比率は、通常、溶解度及び得られる粘度によって決定される。本明細書で開示する転相法における最適な比率は、10部の樹脂に対して、有機溶媒(例えばメチルエチルケトンなど)が約5〜約7部であることが分かっている。上記範囲外の比率も使用できる。
なお、本明細書において「部」とは質量部を指す。
