Abstract
Rare earth-transition metal oxides are used as pigments. The rare earth-transition metal oxide pigments are preferably of the formula (Re Tm)O , where Re is at least one rare earth element, Tm is at least one transition metal, x ranges from 0.08 to 12, and y ranges from x+1 to 2x+2. The pigments are useful as colorants, and possess good stability.
