To provide an ink composition and a recording apparatus which are excellent in abrasion resistance and have improved ejection stability by suppressing clogging in a short term and a long term. One embodiment of the present invention is an ink composition including a coloring material, water, and polymer particles, the polymer particles having a core-shell structure including a core polymer and a shell polymer, An ink composition having a glass transition temperature of less than 60 ° C., a glass transition temperature of the shell polymer of 60 ° C. or more, an acid value of the polymer particles of 50 mg KOH / g or more, and the shell polymer containing an aromatic monomer as a constituent unit. It is a thing. [Selection] Figure 1 |
