The ink set for inkjet recording of the invention has at least: an aqueous ink composition containing at least a pigment; and a reaction liquid containing at least a reactant that produces an aggregate when contacted with the aqueous ink composition. The static surface tension of the reaction liquid is 40 mN/m or higher. The dynamic surface tensionγ0.1 is from 40 mN/m to 50 mN/m and the ratioγ0.1/γ10, that is a ratio of the dynamic surface tension and is sometimes referred to asγ, is from 1.01 to 1.10, in which the dynamic surface tension of the reaction liquid at a surface lifetime of 100 ms and 10000 ms isγ0.1 andγ10, respectively, according to the maximum bubble pressure technique. The aqueous ink composition aggregates by contacting the reaction liquid to form an image. |
