Abstract
An aqueous ink for ink jet including a resin particle. The resin particle has a first layer and a second layer in this order from the inside toward the outside of the resin particle. The first layer is formed of a first resin in which the proportion of a unit derived from a cycloaliphatic-group-containing ethylenically unsaturated monomer is 10% by mass or less. The tetrahydrofuran-insoluble fraction of the second layer is 15% by mass or more. The second layer is formed of a second resin having the unit derived from the cycloaliphatic-group-containing ethylenically unsaturated monomer and a unit derived from an ionic-group-containing ethylenically unsaturated monomer. The proportion of the unit derived from the ionic-group-containing ethylenically unsaturated monomer in the second resin is 3% by mass or more to 70% by mass or less.
