Abstract
A colored resin particle dispersion and an ink are provided which exhibit excellent abrasion resistance of the printed items and excellent storage stability of the dispersion. Specifically provided is a colored resin particle dispersion comprising colored resin particles containing a colorant and a solid resin, a basic dispersant, and a non-aqueous solvent, wherein the solid resin is a resin having alkoxy groups and/or a polysilsesquioxane. The resin having alkoxy groups preferably has methoxy groups and/or ethoxy groups. Further, the resin having alkoxy groups preferably contains at least one of a polyamide resin having methoxymethyl groups, a methoxypolysilsesquioxane and an ethoxypolysilsesquioxane.
