Abstract
Official abstract text for this publication.
An ink containing a first coloring material and a second coloring material, the sum total of these contents being 6.0% by mass or less. The first coloring material is a black coloring material exhibiting a difference Δλ max1 of 20.0 or more between a maximum absorption wavelength in a 20.0% by mass aqueous solution of 1,2-hexanediol and a maximum absorption wavelength in water, the second coloring material is a specific coloring material exhibiting a difference Δλ max2 of 12.0 or less between a maximum absorption wavelength in a 20.0% by mass aqueous solution of 1,2-hexanediol and a maximum absorption wavelength in water, and the sum of the Δλ max1 and the Δλ max2 is 35.0 or less.
First claim
Opening claim text (preview).
What is claimed is: 1. An ink jet ink comprising a first coloring material and a second coloring material, wherein the first coloring material is a black coloring material exhibiting a difference Δλ max1 (=λ maxD1 −λ maxW1 ) of 20.0 or more between a maximum absorption wavelength (λ maxD1 ) in a 20.0% by mass aqueous solution of 1,2-hexanediol and a maximum absorption wavelength (λ maxW1 ) in water in a UV-Vis absorption spectrum; wherein the second coloring material is a color…
