Abstract

A coloring composition includes a pigment, a resin, and a curable compound, in which the pigment includes a red pigment, a yellow pigment, and an orange pigment, and a mass ratio of the yellow pigment to the red pigment and a mass ratio of the orange pigment to the red pigment in the coloring composition are yellow pigment/red pigment=1.0 to 2.0/1.0 and orange pigment/red pigment=0.9 to 2.0/1.0, respectively.

Claims

1. A coloring composition comprising:

a pigment;

a resin; and

a curable compound,

wherein the pigment includes a red pigment, a yellow pigment, and an orange pigment, and
