The formed body is, further, blended with a non-lustrous pigment as the coloring agent, which is different from a lustrous pigment such as flaky pigment, and exhibits a metal color over the foamed region thereof. The foamed formed body exhibiting a metal color and, specifically, a gold color or a silver color is thus provided without using any expensive lustrous pigment such as metal powder pigment or flaky pigment.

The invention provides a synthetic mica based silver pearlescent pigment as well as preparation method and application thereof. A mica substrate is externally coated with a barium sulfate layer, a first tin oxide doped titanium dioxide layer, a titanium dioxide doped silicon dioxide layer and a second tin oxide doped titanium dioxide layer in turn. A structure of alternate coating by high- and low-refractive indexes (tin-titanium oxide / titanium-silicon oxide / tin-titanium oxide) is adopted, but the same hydrolysis conditions are adopted in the coating process of a plurality of oxide layers; thus, the technology is stabilized, and the cost is remarkably saved. By adopting titanium dioxide doped silicon dioxide on the low-refractive index layer to form a semitransparent middle interlayer, thepigment gloss is improved while the covering power is noticeably enhanced; the base material is coated by a layer of semitransparent barium sulfate, and unexpectedly, the covering power is further enhanced; therefore, the silver pearlescent pigment has the advantages of high gloss, strong covering power and the like.
