Abstract
A resin particle dispersion containing core/shell-type resin particles and water is described. A shell portion resin of the core/shell-type resin particles contains a constitutional unit derived from a (meth)acrylic acid ester containing a hydrocarbon group having from 4 to 8 carbon atoms. A core portion resin of the core/shell-type resin particles contains a constitutional unit derived from a (meth)acrylamide-based monomer whose solubility parameter lies within the range of from 17.0 to 21.0 (J/cm)in an amount of not less than 5% by mass, and a glass transition temperature of the core portion resin is not higher than 50° C. An acid value of the core/shell-type resin particles is from 50 to 100 mgKOH/g. A process for producing the resin particle dispersion and a printing method using the resin particle dispersion is also described.
