Highly versatile composite fine particles that can coexist with a wide variety of other components, a dispersion thereof, and a method of producing such a dispersion. Furthermore, by using these composite fine particles, there are also provided a high-quality ink jet recording material and a method of producing this ink jet recording material. Composite fine particles, which include cationic fine particles that exhibit a positive zeta potential when dispersed within water to form a dispersion and an anionic compound that is supported on the surface of the cationic fine particles, wherein the composite fine particles exhibit a negative zeta potential when dispersed within water to form a dispersion, are added to the coating layer of an ink jet recording material.
可与多种其他成分共存的高通用性复合细颗粒、其分散体以及生产这种分散体的方法。此外,通过使用这些复合微粒,还提供了一种高质量喷墨记录材料和生产这种喷墨记录材料的方法。在喷墨记录材料的涂层中加入复合微粒,复合微粒包括阳离子微粒和阴离子化合物,阳离子微粒在水中分散形成分散液时呈现正 ZETA 电位,阴离子化合物在阳离子微粒表面支撑,复合微粒在水中分散形成分散液时呈现负 ZETA 电位。
