Abstract:
1. An ink set for inkjet recording comprising: an aqueous ink composition comprising a pigment; and a reaction liquid comprising a reactant that produces an aggregate when contacted with the aqueous ink composition, the static surface tension of the reaction liquid being 40 mN/m or higher, and the dynamic surface tension γ0.1 being from 40 mN/m to 50 mN/m and the ratio γ0.1/γ10 being 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 is γ0.1 and γ10, respectively, according to the maximum bubble pressure technique, wherein the pH of the reaction liquid is from 0.5 to 2.5.
