发明名称 INK COMPOSITION AND RECORDING APPARATUS
摘要 An ink composition includes a color material, water, and polymer particles, in which the polymer particle has a core-shell structure having a core polymer and a shell polymer, a glass transition temperature of the core polymer is 30° C. or higher, a glass transition temperature of the shell polymer is 50° C. or higher, the glass transition temperature of the shell polymer is more than 10° C. higher than the glass transition temperature of the core polymer, and the core polymer includes an aromatic monomer as a constituent unit and does not substantially include an alkyl polyol having a standard boiling point of 280° C. or higher.
