| description | There are provided: a near-infrared non-absorbing black azo pigment having a sufficient blackness, having an excellent durability such as solvent resistance, and having a novel skeleton; and a colorant that uses the black azo pigment and is useful for forming a black matrix or a light-shielding film. The black azo pigment is represented by the following formula (1), wherein R 1 represents an aryl group optionally having a substituent. In addition, the colorant contains the black azo pigment and is suitable as a material or the like for forming a black matrix for a color filter or for forming a light-shielding film. |
