    • PURPOSE: A pearly pigment and its preparation method are provided, to obtain high brightness and high freshness even in being coated on a thin small plate-type substrate having a fine average diameter. The pearly pigment is applied to a paint, a printing ink, a lacquer, a plastic material, a laser marking dopant, a non-dusting pigment product, a non-dusting pigment granule and cosmetics. CONSTITUTION: The pearly pigment is a multilayer coating having at least two layers of a metal oxide containing at least one kind of metal selected from the group consisting of Ce, Sn, Ti, Fe, Zn and Zr, coated on the surface of a thin substrate. Preferably the lowest layer of the multilayer coating is a metal oxide layer containing a metal selected from the group consisting of Ce, Sn and Fe, and the multilayer coating contains at least one multilayer unit comprising a Sn-containing metal oxide layer and a metal oxide layer containing Ti adhered on the Sn-containing metal oxide layer. Preferably the multilayer coating contains an alkali metal and/or an alkaline earth metal. Preferably the substrate is selected from the group consisting of mica, synthetic mica, silica flake, alumina flake, glass flake, thin small plate-type iron oxide and metal flake.
