Abstract: Disclosed is a pigment composition which comprises (a) a pigment of formula wherein Ar1 is phenylene or C2-C6-heteroarylene, Ar2 is C6-C10-aryl or C2-C6-heteroaryl; and (b) a pigment derivative of formula (PM-C X1). (II), wherein P1 is a residue of a colorant chromophore, X1 is a group comprising an aliphatic carboxamide group, an aliphatic sulfonamide group, a carboxylic acid group or salt thereof, and m is 1, 2, 3 or 4. The pigment composition is suitable to color organic material, especially photosensitive resist formulations for use in color filter applications having high contrast ratios.
