PIGMENT CONTAINING RARE EARTH MANGANESE OXIDE, COATING OR ENAMEL COMPOSITION CONTAINING THE PIGMENT, COATED ARTICLE, METHOD FOR PREPARING THE PIGMENT, AND METHOD OF COLORING ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a pigment having improved color, composition and performance characteristics.SOLUTION: A rare earth manganese oxide is used as a pigment. The pigment is favourably of a formula: (REMn)O, where RE is at least one element selected from Y, La and an element in lanthanum series, x is 0.01 to 99 and y is the number requested for keeping electrical neutrality. The favourable rare earth elements include Y, La, Pr and Nd. The pigment is useful as a colorant and possesses improved reflectance characteristics in the infrared region and thereby IR-induced heat build-up is reduced.
