Claim:
An ink jet image recording method comprising hitting an ink composition on a recording material in condition of at least one of: a hitting volume of 0.1 to 100 pl; an ejection frequency of 1 KHz or more; and an average hitting speed of 2 m/sec or more, the ink composition comprising an aqueous medium and at least one water-soluble dye represented by the following formula (1) which is dissolved in the aqueous medium: wherein A represents a 5-membered unsaturated heterocyclic group and is bonded to the azo group of formula (1) with a carbon atom; B 1 and B 2 each represents ═CR 1 — or —CR 2 ═ or either one of B 1 and B 2 represents a nitrogen atom and the other represents ═CR 1 — or —CR 2 ═; R 5 and R 6 each independently represents a hydrogen atom or a substituent, the substituent is an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an alkylsulfonyl group, an arylsulfonyl group or a sulfamoyl group, and hydrogen atom of each of the substituent may be substituted; G, R 1 and R 2 each independently represents a hydrogen atom or a substituent, the substituent is a halogen atom, an aliphatic group, an aromatic group, a heterocyclic group, a cyano group, a carboxyl group, a carbamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heterocyclic oxycarbonyl group, an acyl group, a hydroxy group, an alkoxy group, an aryloxy group, a heterocyclic oxy group, a silyloxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group, an acylamino group, a ureido group, a sulfamoylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, a heterocyclic sulfonylamino group, a nitro group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkylsulfonyl group, an arylsulfonyl group, a heterocyclic sulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a heterocyclic sulfinyl group, a sulfamoyl group or a sulfo group, and a hydrogen atom of each of the substituent may be substituted; R 1 and R 5 , or R 5 and R 6 may combine to form a 5- or 6-membered ring; and wherein the dye has an ionic hydrophilic group as a substituent on any position of A, R 1 , R 2 , R 5 , R 6 , and G.
