Beschreibung
Zusammenfassung:	The invention provides a cationic emulsion having a polymer core-shell structure that exhibits excellent substrate adhesiveness, water resistance, moisture resistance, alcohol resistance, and high gloss when used in an aqueous ink, and exhibits excellent color developing properties and water resistance when used in a recording medium, specifically, a cationic emulsion having a polymer core-shell structure comprising component (A) and component (B) and having a mass ratio of component (A):component (B) of 25:75-75:25. (A) Emulsion polymer core component obtained by polymerizing a monomer having a vinyl chloride monomer as a constituent. (B) Emulsion polymer shell component having a structure obtained by polymerizing a monomer mixture having, as constituents: styrenes and a compound of formula (1); or styrenes, a compound of formula (1), and a (meth)acrylic ester having 1-22 carbon atoms in the ester part as a compound (2); in which the compound of formula (1) is 20-45 mass% in the monomer mixture.
