and A
2
is independently a moiety which includes a substituted or unsubstituted C
2
-C
30
alkenylene group having at least one double bond and is conjugated with an azo group; each of X
1
and X
2
is selected from the group consisting of a hydroxy group, a C
1
-C
4
alkoxy group, a carboxyl group, and a substituted or unsubstituted amino group; M is a polyvalent transition metal; L is a neutral or anionic ligand; T is a mono- or poly-substituted hydrophilic functional group; n is an integer between 1 and 3; and J is a linker. The self-dispersible metal complex colorant may be used in various fields employing colors, such as fibers, foods, drugs, cosmetics, coatings, inks or ceramics.
