Reaction liquid and ink jet recording method

Abstract

Provided is a reaction liquid for ink jet, which can record a high-quality image and is excellent in intermittent ejection stability, to be used together with an aqueous ink. The reaction liquid for ink jet is used in an ink jet recording method including recording an image on a recording medium with an aqueous ink and an aqueous reaction liquid containing a reactant that reacts with the aqueous ink. The reaction liquid includes a polyvalent metal salt and a surfactant. The surfactant is a compound including a hydrophilic moiety having an anionic group and a hydrophobic moiety that is an aliphatic hydrocarbon group. A mass ratio of a content (% by mass) of the polyvalent metal salt in the reaction liquid to a content (% by mass) of the surfactant therein is 10.0 times or more to 35.0 times or less.
