|Applicants:||NIPPON SHEET GLASS COMPANY, LIMITED
|Title:||LUSTROUS PIGMENT HAVING ELECTROMAGNETIC WAVE-TRANSMITTING CHARACTERISTICS, COMPOSITION CONTAINING THIS PIGMENT, AND COATED BODY|
The present invention provides a lustrous pigment which enables the achievement of a good balance between electromagnetic wave-transmitting properties and appearance having a neutral color with high reflectance. A lustrous pigment according to the present invention comprises: a glass flake 1; and a titanium oxide layer 2 and a silver layer 3, which are sequentially formed on the glass flake 1 in this order. If optical thicknesses are expressed in the unit of nm, the product of the optical thickness of the glass flake 1 and the optical thickness of the titanium oxide layer 2 is from 61,000 to 66,000 (inclusive), while the physical thickness of the silver layer 3 is from 35 nm to 55 nm (inclusive).
