Novel subphthalocyanine colorants, ink compositions, and methods of making the same |
摘要 |
The present invention is directed to methods of making subphthalocyanine compounds. The methods of the present invention may be used to produce known subphthalocyanine compounds, as well as, a new family of subphthalocyanine compounds. The methods of the present invention may employ environmentally-friendly solvents, which donate a hydrogen atom for use in the reaction mechanism. The methods of the present invention produce subphthalocyanine compounds at a yield of greater than about 50%, and even greater than about 94%. The present invention is further directed to subphthalocyanine compounds having improved lightfastness. The subphthalocyanine compounds may have a Subphth-Lightfastness Test Value of less than 15%. |
