A pigment formulation comprises organic pigment consisting of C. I. Pigment Red 297 or C. I. Pigment Orange 80; and pigment dispersing agent. The pigment formulation comprises organic pigment consisting of C. I. Pigment Red 297 of Formula (I) or C. I. Pigment Orange 80 of Formula (II); and pigment dispersing agent consisting of formula (III) or(IV).
