    • The invention relates to color toner compositions prepared from a process for the preparation of a dry toner powder from an aqueous pigment concentrate dispersion comprising: blending at least an aqueous-based pigment concentrate dispersion and a resin to produce a paste; charging the paste to an extruder to generate an extruded pigment/resin mixture; dispersing the extruded pigment/resin mixture in a low boiling organic medium to create an organic phase; dispersing the organic phase in an aqueous phase containing a particulate stabilizer and mixing the organic phase and the aqueous phase at elevated temperature and under shear force to form toner particles of a controlled size and shape; removing the organic solvent and particulate stabilizer from the formed particles; and washing, drying, and collecting the particles for use as a dry toner powder.
    • 本发明涉及由水性颜料浓缩物分散体制备干燥调色剂粉末的方法制备的彩色调色剂组合物,包括:至少混合水基颜料浓缩物分散体和树脂以产生糊状物; 将糊料装入挤出机以产生挤出的颜料/树脂混合物; 将挤出的颜料/树脂混合物分散在低沸点有机介质中以产生有机相; 将有机相分散在含有颗粒稳定剂的水相中,并在高温和剪切力下混合有机相和水相以形成受控尺寸和形状的调色剂颗粒; 从形成的颗粒中除去有机溶剂和颗粒稳定剂; 并洗涤,干燥和收集颗粒以用作干燥调色剂粉末。
