Paragraph 0204; 0205, (2013/10/21)
Provided are a pigment excellent in the light stability, heat resistance, dispersibility, and color reproducibility without containing any metal-containing compound, a compound composing the pigment, and a pigment composition, a coloring composition, a colored radiation-sensitive composition, a color filter, an inkjet ink using the same, and a method of manufacturing colored radiation-sensitive composition. A pigment comprising at least either a compound represented by the formula (I) or a compound represented by the formula (II) below, the compound showing an absorbance of 0.5 or below at a wavelength of absorption maximum in the range from 300 to 700 nm, when contained in a filtrate obtained after adding 0.01% by weight of the compound into water, and, obtained after adding 0.01% by weight of the compound into 1-monomethyl ether 2-acetate, respectively followed by stirring at 25°C for 10 minutes, and filtering through a filter with a pore size of 0.20 μm. In the formulae (I) and (II), each of R1 to R12 independently represents a monovalent substituent.
