摘要 |
An ink composition contains a pigment; a copolymer containing a phosphoric acid group or phosphonic acid group; a hydrosoluble solvent; and water, wherein the pigment is represented by the following chemical formula 1 and satisfies the following relation 1: Y<X<0.8, where X represents a peak intensity at a Bragg (2θ±0.2°) angle in a range of 2θ of from 5.5° to 6.0° and Y represents a peak intensity at a Bragg (2θ±0.2°) angle in a range of 2θ of from 26.5° to 27.5° to a CuKα X-ray having a wavelength of 1.541 Å.;where R each, independently represents monovalent groups selected from hydrogen atoms, methyl groups, or chlorine atoms. |

1. An ink composition comprising:
a pigment; a copolymer comprising a phosphoric acid group or phosphonic acid group; a hydrosoluble solvent; and water, wherein the pigment is represented by the following chemical formula 1 and satisfies the following relation 1:
Y<X<0.8 Relation 1 where X represents a peak intensity at a Bragg (2θ±0.2°) angle in a range of 2θ of from 5.5° to 6.0° and Y represents a peak intensity at a Bragg (2θ±0.2°) angle in a range of 2θ of from 26.5° to 27.5° to a CuKα X-ray having a wavelength of 1.541 Å. where R each, independently represents monovalent groups selected from hydrogen atoms, methyl groups, or chlorine atoms. |
