Rare earth manganese oxides are used as pigments.nThe pigments are preferably of the formula (Re x Mn)O y , wherenRe is at least one element selected from Y, La andnLanthanide elements, x is from 0.01 to 99, and y is thennumber required to maintain electroneutrality. Preferrednrare earth elements include Y, La, Pr and Nd. The pigmentsnare useful as colorants, and may possess improvednreflectance characteristics in the infrared region, therebynreducing IR-induced heat buildup. |
