To provide a self-dispersing metal complex coloring agent that can be well dispersed in a solution without a separate dispersing agent. A self-dispersing metal complex coloring agent of Formula 1 in which an azo moiety is bonded to a colorant, a metal is coordinated through the azo moiety, and a self-dispersing ligand is bonded to the metal is provided. In the formula, COLORANT means a colorant, Ar and A 2 each contain an alkenylene group, and X 1 and X 2 each represent a hydroxy group, a carboxyl group or an amino group. M represents a polyvalent transition metal and L represents a neutral or negative ligand. T represents a hydrophilic functional group, and n is an integer of 1-3. J represents a linker.
