Abstract:
1. An ink jet recording method comprising: applying a yellow ink and a cyan ink to a recording medium, the yellow ink containing, as a coloring material, at least one compound selected from compounds of the following A group and at least one compound selected from compounds of the following B group, and having a surface tension of 33.0 mN/m or more and 36.0 mN/m or less; and the cyan ink containing, as a coloring material, a phthalocyanine compound represented by the following general formula (1) or (2), containing 1,5-pentanediol as an organic solvent, and having a surface tension of 32.9 mN/m or more and 35.4 mN/m or less; A group: C.I. Direct Yellow 132 and C.I. Direct Yellow 173 B group: C.I. Direct Yellow 142, C.I. Direct Yellow 86 and a compound represented by the following general formula (3) wherein l represents 0 to 2, m represents 1 to 3, and n represents 1 to 3 provided that l+m+n=3 to 4; a substitution position of a substituent is 4-position or 4′-position; M represents an alkali metal or ammonium; R 1 and R 2 each independently represent a hydrogen atom, a sulfonic acid group, and a carboxyl group provided that R 1 and R 2 are not simultaneously a hydrogen atom; Y represents a chlorine atom, a hydroxyl group, an amino group, or a monoalkylamino or dialkylamino group; wherein M is a counter ion of a sulfonic acid group, and represents a hydrogen atom, an alkali metal, ammonium, or organic ammonium; wherein m each independently represents 1 or 2; and M1 represents a hydrogen atom, an alkali metal, an alkali earth metal, a cation of organic amine or an ammonium ion.
