    • A solid dispersion of pigment in granular form may include: at least one pigment; and at least one cold-water-soluble modified starch. A method for preparing an aqueous composition including at least one pigment may include: combining the at least one pigment, at least one cold-water-soluble modified starch, and water. A process for preparing a solid dispersion of pigment in granular form may include: mixing at least one pigment, at least one cold-water-soluble modified starch, and water to form a paste; and/or grinding the paste and evaporating at least part of the water to obtain the solid dispersion. A process for using at least one cold-water-soluble modified starch may include: preparing a solid dispersion of pigment in granular form by combining at least one pigment, the at least one cold-water-soluble modified starch, and water; and/or using the at least one cold-water-soluble modified starch as a carrier agent in the solid dispersion.
    • 颗粒状颜料的固体分散体可包括:至少一种颜料; 和至少一种冷水溶性改性淀粉。 制备包含至少一种颜料的水性组合物的方法可以包括:将至少一种颜料,至少一种冷水溶性改性淀粉和水组合。 制备颗粒状颜料的固体分散体的方法可包括:将至少一种颜料,至少一种冷水溶性改性淀粉和水混合以形成糊状物; 和/或研磨浆料并蒸发至少部分水以获得固体分散体。 使用至少一种冷水可溶性改性淀粉的方法可包括:通过将至少一种颜料,至少一种冷水可溶性改性淀粉和水组合而制备颗粒状颜料的固体分散体; 和/或在固体分散体中使用至少一种冷水可溶性改性淀粉作为载体剂。
