摘要： An object to be achieved by the present, invention is to provide a quinacridone pigment having hue that is yellowish and clear and having excellent storage stability, wherein the quinacridone pigment can be advantageously used in an ink-jet ink and the like. Provided is a quinacridone solid solution pigment comprising at least C. I. Pigment Violet 19 and C. I. Pigment Red 122, wherein the ratio of a diffraction peak intensity at a diffraction angle 2θ of 14.8±0.2° to a diffraction peak intensity at a diffraction angle 2θ of 11.9±0.2° is 1.20 or less, as measured by X-ray diffractometry with respect to the quinacridone solid solution pigment.
