Latest Patents

One of Minami's latest patents focuses on a method for producing quinacridone solid solution pigment, pigment dispersion, and inkjet ink. This innovative technique allows for the creation of a quinacridone solid solution pigment that yields a colored product with high chroma and a bluish hue. The method involves several steps, including the co-cyclization reaction of diarylaminoterephthalic acid and dialkylarylaminoterephthalic acid in polyphosphoric acid. This process results in a water-containing crude quinacridone solid solution, which is then dried to reduce water content to less than 1%. Finally, the pigment is produced by heating the powdery crude quinacridone solid solution in a liquid medium that does not dissolve it.
