Recording method
A recording method includes first coating a treatment liquid A to a recording medium, a second coating a treatment liquid B to the recording medium after the first coating, and a discharging an ink composition including a coloring material to the recording medium by discharging from a nozzle after the second coating, and the treatment liquid A adjusts wettability of the treatment liquid B to the recording medium and includes at least any one of a resin and inorganic oxide fine particles, and the treatment liquid B thickens or insolubilizes the ink composition and includes at least any one of a polyvalent metal salt, an organic acid, and an organic acid salt.
1. A recording method comprising:
first coating a treatment liquid A to a recording medium,
wherein the treatment liquid A includes a resin, and a SP value of the resin is 14 or less;
second coating a treatment liquid B to the recording medium after the first coating; and
discharging an ink composition including a coloring material to the recording medium by discharging from a nozzle after the second coating,
wherein the treatment liquid A adjusts wettability of the treatment liquid B to the recording medium and includes at least any one of a resin and inorganic oxide fine particles, and
the treatment liquid B thickens or insolubilizes the ink composition and includes at least any one of a polyvalent metal salt, an organic acid, and an organic acid salt.
2. The recording method according to claim 1 ,
wherein the treatment liquid A includes the resin, and a glass transition temperature of the resin is 29° C. or lower.
3. The recording method according to claim 1 ,
wherein the treatment liquid B includes the polyvalent metal salt.
