SOLUTION: In a coloring composition for image recording containing a pigment and a resin, as the pigment, a diazonium salt of p-toluidine-m-sulfonic acid and β-oxynaphthoic acid are coupled, and after coupling, or Lake with calcium at the same time as the ring I. Pigment Red 57: 1, p-toluidine-m -An azo lake pigment composition obtained by substituting a part of sulfonic acid with a benzene-based amine having a polar group such as 4-amino-benzamide or the like, characterized by using an azo lake pigment composition. |
