Abstract
The present invention provides a new glitter pigment suitable for providing high-brightness whitish reflected light. The glitter pigment according to the present invention includes: a flaky substrate; and a silicon oxide layerand a titanium oxide layerformed in this order on the flaky substrate, wherein in the case where the flaky substrate is the glass flake, the glass flake has a thickness of 284 to 322 nm, the silicon oxide layer has a thickness of 89 to 109 nm, and the titanium oxide layer has a thickness of 51 to 86 nm. In the case where the flaky substrate is the alumina flake, the alumina flake has a thickness of 260 to 280 nm, the silicon oxide layer has a thickness of 79 to 102 nm, and the titanium oxide layer has a thickness of 47 to 87 nm.
