Abstract:
1. An ink jet recording method comprising: an image formation step of forming an image on a recording medium having an ink-receiving layer by ejecting an ink from an ink jet recording head; and a humidification step of humidifying a gap between the recording head and the recording medium, wherein in the image formation step, at least a cyan ink containing a dye represented by general formula (I) and a magenta ink containing a dye represented by general formula (II) are used: wherein in general formula (I), A, B, C, and D each independently represent a six-membered ring having aromaticity, and at least one of A, B, C, and D represents a pyridine ring or a pyrazine ring; M's each independently represents a hydrogen atom, an alkali metal, ammonium, or organic ammonium; E represents an alkylene group; X represents a sulfo-substituted anilino group, a carboxy-substituted anilino group, or a phosphono-substituted anilino group, and the substituted anilino group may further contain one to four substituents of at least one type of substituent selected from the group consisting of a sulfonic acid group, a carboxy group, a phosphono group, a sulfamoyl group, a carbamoyl group, a hydroxy group, an alkoxy group, an amino group, an alkylamino group, a dialkylamino group, an arylamino group, a diarylamino group, an acetylamino group, an ureido group, an alkyl group, a nitro group, a cyano group, a halogen atom, an alkylsulfonyl group, and an alkylthio group; Y represents a hydroxy group or an amino group; and a, b, and c satisfy 0≦a≦2.0, 0≦b≦3.0, and 0.1≦c≦3.0, provided that a+b+c=1.0 to 4.0 and general formula (II) wherein in general formula (II), R 1 , R 2 , R 3 , and R 4 each independently represent an alkyl group; and M's each independently represent a hydrogen atom, an alkali metal, ammonium, or organic ammonium.
