Image recording method, ink set, and method for preparing ink set

摘要

An image recording method includes a conveyance process for conveying a recording medium and an ink-applying process for applying a first ink and a second ink to the recording medium, wherein the first ink and the second ink contain a surfactant represented by Formula (1), the amount of the surfactant represented by Formula (1) in the first ink is greater than the amount of the surfactant represented by Formula (1) in the second ink, and a liquid X prepared by removing the surfactant represented by Formula (1) from the first ink and a liquid Y prepared by removing the surfactant represented by Formula (1) from the second ink satisfy a particular condition.

1. An image recording method, comprising:
a conveyance process for conveying a recording medium; and an ink-applying process for applying a first ink and a second ink to the recording medium, wherein the first ink and the second ink comprise a surfactant represented by Formula (1)
R1 (CR2R3)nCH2CH2(OCH2CH2)mOH  (1), wherein, in the general formula (1), R1 denotes a fluorine atom or a hydrogen atom, R2 and R3 independently denote a fluorine atom or a hydrogen atom, and at least one of R2 and R3 denotes a fluorine atom, n is 1 or more and 30 or less, and m is 1 or more and 60 or less, the amount of the surfactant represented by Formula (1) in the first ink is greater than the amount of the surfactant represented by Formula (1) in the second ink, and a liquid X prepared by removing the surfactant represented by Formula (1) from the first ink and a liquid Y prepared by removing the surfactant represented by Formula (1) from the second ink satisfy the following condition: wherein when performing recording on a recording medium having a water absorption rate coefficient Ka of 0.1 mL/m2·ms1/2 or more and 0.3 mL/m2·ms1/2 or less such that a liquid X recording area comes into contact with a liquid Y recording area, the liquid Y flows from the liquid Y recording area into the liquid X recording area.
