A black dye for ink-jet recording which comprises a metal chelate azo dye whose free-acid form is represented by the general formula (1) and which combines satisfactory achromaticity with satisfactory light resistance; and a recording fluid containing the dye. (The general formula (1) shows a molecule having one or more hydrophilic groups. In the formula (1), M represents any metal; A, B, and C each represents an aromatic ring optionally having any substituent; D represents an aromatic ring optionally having any substituent other than an azo group; R1 and R2 each represents hydrogen or any substituent; m is an integer of 0 or 1; n is an integer of 0 to 3; p is an integer of 0 to 2; and q is an integer of 1 to 3; when two or more B's are present, they may be the same or different; M can have three or more coordination bonds with any part or ligand contained in the general formula (1); and a metal ion may be further coordinated, in the form of -O-M-O-, to A and B, or to two B's spaced by an azo group when there are two or more B's, or to B and C).
