Production process for colorant, colorant composition, toner, ink for ink jet recording and color filter
Abstract:
Provided is a production process for a colorant which contains a silicon phthalocyanine compound making it possible to reach a targeted particle diameter even by a conventional dispersing method and which is excellent in performances such as a color reproducibility, a light fastness, an electrostatic property, a transparency and the like, and a colorant composition, a toner, an ink for ink jet recording and a color filter which are excellent in the above performances.The above production process is a production process for a colorant containing a silicon phthalocyanine compound and a copper phthalocyanine compound and is characterized by having a preparing step of reacting raw materials of a silicon compound and phthalocyanine under the presence of a copper salt or the copper phthalocyanine compound described above to prepare the silicon phthalocyanine compound described above.
