Latest Patents
Hideko Noguchi holds a patent for a process for the production of phthalocyanine pigment. This process is designed to create a pigment with a clear color tone, high tinting strength, and a finely milled structure. The method allows for the pigmentation from a phthalocyanine crude without the need to remove the aromatic hydrocarbon solvent used in its synthesis. The steps include reacting phthalic anhydride or its derivative, urea or its derivative, and a catalyst in an organic solvent to synthesize the phthalocyanine crude. Following this, the slurry of the synthesized crude is wet-milled in the presence of a milling medium, and finally, the organic solvent is removed from the slurry of the milled product, which is then purified and dried using a spray type dryer. This innovative approach not only improves the production process but also makes it more economical.
