2. Description of the Related Art When fine particles of pigment are dispersed in non-aqueous vehicles such as offset inks, gravure inks, and paints, it is difficult to obtain a stable dispersion, and this is a problem in terms of manufacturing operations and the value of the resulting product. It is known to cause various problems that have significant effects. For example, a dispersion containing a pigment composed of fine particles often has a high viscosity, which not only makes it difficult to remove and transport the product from the disperser, but also worse, causes gelation during storage and causes use. It can be difficult. When different kinds of pigments are mixed and used, color unevenness or marked reduction in coloring power may be caused in a colored product due to phenomena such as color separation due to aggregation and precipitation. Pigment dispersants in which various substituents are introduced into pigments to solve the above problems are known, but effective pigment dispersants are known for yellow pigments, particularly benzimidazolone pigments.
