Patent number: 6368395Abstract: 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%.Type: GrantFiled: May 12, 2000Date of Patent: April 9, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ronald Sinclair Nohr, John G.
