PIGMENT SIMULTANEOUSLY HAVING HIGH BRIGHTNESS, COLOR PURITY AND COVERAGE EFFECT AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2020/001010

Kind Code:

A1

Abstract:

The present invention relates to a pigment simultaneously having high brightness, high color purity and high coverage effect. The pigment comprises a core material and an outer cladding layer. The core material has a structure of 1-20 layers, and comprises an air layer, and/or one of the following three layers: a dielectric layer, a reflective layer, and a multilayer structure composed of the dielectric layer and one layer of the reflective layer. The total thickness of the core material is 20-1000 nm. The single layer thickness of the dielectric layer is 50-300 nm. The single layer thickness of the reflective layer is 20-100 nm. The total thickness of the core material and the single layer thickness of the dielectric layer or the reflective layer deviate by no more than 1% or 5 nm of the average of the total thickness and the corresponding layer thickness. One to six layers of the outer cladding layer are comprised, the total thickness of the outer cladding layer is 20-1000 nm, and the thickness of each cladding layer is 10-300 nm. The pigment of the present invention can be used in coatings, inks, cosmetics, and make-up products.
