Abstract
Alkaline earth-manganese oxides are used as pigments. The alkaline earth-manganese oxide pigments are preferably of the formula Me MnO , where Me is at least one metal selected from Ca, Sr, Ba and Mg, x is from 0.01 to 99, and y is greater than or equal to x+1 and less than or equal to x+2. The pigments are useful as colorants, and also possess improved reflectance characteristics, particularly in the IR region, and may reduce IR-induced heat buildup. These colorants can be used to form colored objects, or coat objects when they are either added into or applied onto materials such as paints, inks, plastics, glasses, ceramics and the like. The patent also covers the production of these pigments.
