Latest Patents
Robertson holds a patent for a "Process for preparing nanoscale quinacridone." This invention relates to a method for the production of nanoscale size quinacridones through a wet-salt attrition process. The process involves combining a crude quinacridone pigment with an inorganic salt, an organic liquid in which both the quinacridone pigment and salt are substantially insoluble, and a quinacridone derivative in an amount less than 10 wt. % relative to the quinacridone pigment. The method includes discharging the ground quinacridone pigment into water, adding an acid to produce a solution pH of 1.5 or lower, and isolating the quinacridone pigment. This innovative process enhances the efficiency and quality of quinacridone production.
