Metal chelated dyestuff for inkjet recording, aqueous inkjet recording liquid comprising same and inkjet recording method using same

A metal chelated dyestuff for inkjet recording which is a water soluble azo metal chelated compound formed by an azo-based compound the free acid form of which is represented by the following general formula (1) and having one or more hydrophilic group per molecule and a metal element:

• wherein X1 represents a chain of a plurality of atoms containing a total of 2 or more hetero atoms of one or more kinds selected from the group consisting of nitrogen atom, oxygen atom and sulfur atom and required to form at least one 5- to 7-membered heterocyclic ring;
• the heterocyclic ring containing X1 may have substituents thereon;
• the substituents on the heterocyclic ring may further be condensed to form a condensed ring;
• the condensed heterocyclic ring containing X1 may be substituted, with the proviso that the heterocyclic ring containing X1 is not a heterocyclic ring represented by the following general formula (2) or (3);
• and Ar1 represents naphthyl group represented by any one of the following general formulae (4) to (6):
• wherein R represents hydrogen atom or arbitrary substituent;
• wherein Y1 represents a chelating group;
• Z1's represent arbitrary substituents which may be different from each other;
• and a represents an integer of from 0 to 6.
