摘要:
A pearlescent pigment comprising a substrate and a first layer, wherein the first layer comprises iron oxide, wherein the iron has from about 1% to about 30% Fe(II) and from about 70% to about 99% Fe(III). A process for making these pearlescent pigment, comprise reducing a metal oxide substrate with a hydrogen source in the presence of a noble metal catalyst in a liquid medium. The pigments may be used in a variety of applications including cosmetics, plastics, automotive, or architectural coatings.

摘要:
A pearlescent pigment, wherein the pigment is an inorganic material and the color of a homogeneous coating of the pigment, measured over a white background, is selected from the group consisting of: a CIELAB L* value of about 30 or less and a chroma value of about 3 or less; a CIELAB hue angle, hab, from about 50 to about 80 degrees, wherein L* is not more than about 85, and the chroma value is greater than 22; a CIELAB hue angle, hab, from about 80 to about 275 degrees, wherein L* is not more than about 80, and the chroma value is greater than about 10; and a CIELAB hue angle, hab, from not less than about 275 to not more than about 50 degrees, wherein L* is not more than about 85, and the chroma value is greater than about 9. The pigments may be used in a variety of applications including cosmetics, plastics, automotive, or architectural coatings.
