Abstract:
A process for preparing a color toner for developing an electrostatic image comprising polymerizing monomers to form primary resin particles, wherein the color toner comprises the primary resin particles and a metal complex dye represented by the following formula (1) or formula (2), ##STR23##wherein, X.sup.1 and X.sup.3 each are a group of atoms bonding with each other which can form at least bidentate coordination bond with a metal ion; y.sup.1 represents an aromatic hydrocarbon ring, a 5- or 6-membered heterocyclic ring or --L.sup.4.dbd.Y.sup.2 ; Y.sup.2 and Y.sup.3 each represent an aromatic hydrocarbon ring or a 5- or 6-membered heterocyclic ring; L.sup.1 and L.sup.4 each represent a substituted or an unsubstituted methine group, or a nitrogen atom; L.sup.2 and L.sup.3 each represent a substituted or an unsubstituted methine group; M represents a metal ion which can form at least a bidentate coordination bond with said group of atoms bonding with each other represented by X.sup.1 and X.sup.3 ; m represents an integer of 0, 1, 2 or 3; n1 and n2 each represent an integer of 1, 2 or 3.
