Abstract
A Cu—Cr—Zn—O based pigment includes a Cu—Cr—O based oxide and Zn derived from a zinc oxide added as a modifying oxide and solid-dissolved in the Cu—Cr—O based oxide. The Cu—Cr—Zn—O based pigment has a composition formula of aCuO·bCr2O3·cZnO (mol %), in which 0.1≤c≤5, 45≤a+c≤55, and 45≤b≤55 (a+b+c=100).
