    • PURPOSE: A pigment ink containing the microcapsulated pigment and its preparation method are provided, which pigment ink shows excellent density, fineness, transparency, coloring, color rendition and dispersion stability with time. CONSTITUTION: The pigment ink comprises a coloring agent containing the pigment particle whose some or total surface is coated with polyhydroxyalkanoate; and a solvent for the dispersion of the coloring agent. Preferably the polyhydroxyalkanoate comprises at least one monomer unit selected from the monomer units represented by the formulas 1 to 3. The method comprises the steps of preparing polyhydroxyalkanoate by using 3-hydroxyacyl CoA as a substrate in the presence of the polyhydroxyalkanoate synthesis enzyme fixed to the surface of the pigment particles dispersed into an aqueous medium, to obtain the coloring agent; and dispersing the coloring agent into the medium for the dispersion of the coloring agent.
    • 目的:提供含有微胶囊颜料的颜料油墨及其制备方法,该颜料油墨具有优异的密度,细度,透明度,着色力,显色性和分散时间稳定性。 构成:颜料墨包含含有颜料颗粒的着色剂,其一些或全部表面涂覆有聚羟基链烷酸酯; 和用于分散着色剂的溶剂。 优选地,聚羟基链烷酸酯包含至少一种选自由式1至3表示的单体单元的单体单元。该方法包括以下步骤:在聚羟基链烷酸酯合成酶存在下,通过使用3-羟基酰基CoA作为底物制备聚羟基链烷酸酯 将颜料颗粒的表面分散在水性介质中,得到着色剂; 并将着色剂分散到用于分散着色剂的介质中。
