PROBLEM TO BE SOLVED: To provide a self-dispersible metal complex coloring agent sufficiently dispersible in a solution without using any special dispersant. SOLUTION: The self-dispersible metal complex coloring agent is obtained by combining an azo moiety to a coloring agent, coordinately combining a metal through the azo moiety and combining a self-distributing ligand to the metal and is represented by chemical formula 1. (Wherein, COLORANT is a coloring agent; A 1 and A 2 each contain an alkenylene; X 1 and X 2 are hydroxy, carboxy or amino; M is a polyvalent transition metal; L is a neutral or anionic ligand; T is a hydrophilic functional group; n is an integer of 1-3; and J is a linker.).

摘要:
A method for producing an azo metal complex dye wherein an azo dye having a partial structure represented by general formula (A) and a metal ion are reacted in the presence of a secondary amine, thereby obtaining a complex of the azo dye and the metal ion. In general formula (A), Q1 represents an atomic group forming a nitrogen-containing heterocyclic ring together with an adjacent nitrogen atom and carbon atom; Y1 represents a hydrogen atom which may be dissociated during formation of the azo metal complex dye; and * represents the bonding position with an -N=N- group.
摘要:
A WORM-type recording layer in an optical information recording medium contains at least one azo-metal complex dye derived from a metal ion and a compound represented by the following general formula (1-1) or (1-2): wherein Q represents a carbocyclic group or a heterocyclic group, and R6 to R8 independently represent a hydrogen atom or a substituent. The compound represented by the general formula (1-1) or (1-2) has a dissociative hydrogen atom in Q, and the dissociative hydrogen atom in Q and the hydrogen atom in the —NH— group marked with asterisk * are eliminated from the compound, so that the residue is bonded to the metal ion to generate the azo-metal complex dye. The azo-metal complex dye may contain a component other than the metal ion and the compound represented by the general formula (1-1) or (1-2).
