摘要

The present invention provides a colorant for inkjet inks which is free from mechanical selectivity, high in light-durability, high in reliability and low in cost. By paying attention to the chemical properties of coloring matter substances and utilizing the technical rules accumulated in the past faithfully to the properties of the coloring matter substances, an epoch-making process for producing fine-particulate colorants by a method comprising five simple steps is provided.
