Ink and sheet for ink jet recording and ink jet recording method

A method of recording an image on a recording sheet, the method comprising

• jetting an ink from a nozzle onto at least image portions of the recording sheet, the ink comprising a compound containing a metal ion capable of co-ordinate bonding with a dye in two or more coordination positions;
• and
• then jetting a recording ink from a nozzle, the recording ink comprising the dye capable of co-ordinate bonding with the metal ion in two or more coordination positions to record the image on a recording sheet, wherein the dye is selected from the group consisting of the following formulas (1) through (9):
• ##STR4## wherein X.sup.1 represents an atomic group necessary to form a 5- to 7-membered heterocyclic or aromatic carbocyclic ring in which at least one position adjacent to the carbon atom bonding with an azo group is substituted with a nitrogen, oxygen, sulfur, selenium or tellurium atom;
