Abstract: A new yellow pigment excellent in both brightness and coloring power is provided. It has been found that dimerization of a specific quinophthalone skeleton gives more selective absorption and transmittance. Furthermore, the dimerization method was also studied, and it has been found that excessive reddish tone can be suppressed by cleaving the conjugate using a methylene chain as a spacer instead of simply employing a direct bond. In addition, dispersibility has been improved by polyhalogenation and introduction of an imide structure. Furthermore, a coloring agent containing the quinophthalone compound and a coloring composition containing the coloring agent are provided.

Abstract: A method for separating a colored resin composition is provided, which can easily separate a colored resin composition into a color pigment and a resin and can implement energy-saving and efficient material recycling. In the method for separating a colored resin composition, a resin is dissolved from a colored resin composition containing a condensed polycyclic organic pigment and/or carbon black into a liquefied solvent containing one or two or more of liquid dimethyl ether, liquid propane, and liquid butane, and the condensed polycyclic organic pigment and/or carbon black and the resin are separated.

Abstract: Provided are a phthalocyanine pigment that is non-water soluble and has antibacterial or antiviral effect, and inks, printed matter, paints, coatings, plastics, fibers, films, cosmetics, and the like containing the pigment. A specific phthalocyanine pigment has antibacterial or antiviral effect, although the pigment is non-water soluble, and has significantly high performance in terms of heat resistance and light fastness, compared with a dye-based antibacterial colorant, because of being a pigment. Because of being a pigment, the phthalocyanine pigment also has antibacterial and antiviral effects in applications such as inks, printed matter, paints, coatings, plastics, fibers, films, and cosmetics, thus achieving the task described above.

Abstract: The halogenated zinc phthalocyanine pigment is for use as a green pigment for color filters and capable of achieving high brightness. In the halogenated zinc phthalocyanine pigment, when a coating film containing 1.00 part by mass of the pigment, 0.95 parts by mass of a benzyl methacrylate-methacrylic acid copolymer, and 0.30 parts by mass of a dimethylaminoethyl methacrylate copolymer is heated at 230° C. for one hour to form an evaluation coating film having a thickness of 4 μm, an average scattering intensity at scattering angles 2θ in a range of 17° to 21° is determined from a two-dimensional scattering image obtained by GI-WAXS measurement of the evaluation coating film, and a normalized average scattering intensity is determined such that the average scattering intensity at an azimuth of 45° is 1, the normalized average scattering intensity at azimuths of 5° to 89° is 0.70 to 1.15.

Abstract: Provided are a quinacridone pigment having a low content of a primary aromatic amine, a method for producing the same, and also a gravure and flexo ink, a colorant for plastic, a paint, a lithographic ink, a toner, or an ink-jet ink using the pigment. The quinacridone pigment having a low primary aromatic amine content is provided by washing a quinacridone pigment with at least one solvent selected from water and an organic solvent, or by adding an oxidizing agent to a pigment slurry including a quinacridone pigment and at least one solvent selected from water and an organic solvent to oxidatively decompose the aromatic amine.
