Abstract
[Object]To provide an ink composition that has excellent performances such as anti-blurring and scratch resistance of markings and is suitable for industrial production.[Resolution Means]Provided are: composite colored particles including resin particles carrying a positive electric charge on particle surfaces and dye-containing particles carrying a negative electric charge on particle surfaces, the resin particles and the dye-containing particles forming a composite through Coulomb force; a water-based ink composition containing the composite colored particles dispersed in a water-based medium; and a writing instrument containing the water-based ink composition.Furthermore, a method of producing composite colored particles, including forming a composite by mixing a resin emulsion containing resin particles carrying a positive electric charge on particle surfaces and a colored resin dispersion containing dye-containing particles carrying a negative electric charge on particle surfaces is provided.
