Coloring composition for image formation and method for improving ozone resistance of color image |
摘要 |
A coloring composition for image formation comprising an azo dye having an aromatic nitrogen-containing 6-membered heterocyclic ring as a coupling component, a coloring composition which comprises an azo compound having an oxidation potential nobler than 1.0 V vs. SCE and comprising at least two substituents having a pKa value of -10 to 5 in water, and a method for improving ozone resistance of a color image, the method comprising using a compound having an oxidation potential nobler than 1.0 V vs. SCE and showing a maximum absorption at a wavelength between 500 nm and 580 nm with a half-value width of 150 nm or narrower.
