A pearlescent pigment for security purposes according to an embodiment of the present invention includes a single or a plurality of coating layers containing a metal oxide and an organic or inorganic fluorescent material. Since the pearlescent pigment for security purposes according to the present disclosure includes a fluorescent layer containing the organic or inorganic fluorescent material, it can be used as a pigment for security purposes due to its optical characteristics and can also provide effects such as magnetism, high color intensity, multiple colors, etc. Also, since the pearlescent pigment for security purposes has aesthetic benefit and security characteristic at the same time, it is economical, easy to use and applicable in various industries.

Pearlescent pigment for security purposes including organic or inorganic fluorescent material

Disclosed is a method for manufacturing plate &#x3b1;-alumina pearlescent pigments and nano-metal coating pearlescent pigments with a large aspect ratio, having excellent reflectivity and capable of expressing various colors.

Method for manufacturing plate alpha-alumina pearlescent pigments and nano-metal coating pearlescent pigments with large aspect ratio

The present invention relates to a nacreous pigment and a method of preparing the same. The nacreous pigment includes a flake substrate, a first metal oxide layer coated on the substrate, and an oxide layer coated on the first metal oxide layer and containing MgO.SiO2, and a second metal oxide layer coated on the oxide layer. The pigment exhibits high brightness, high chroma, high gloss, and multi-color effects.

The present invention relates to a pigment paint for an exterior material and to a method for manufacturing the same. The pigment paint comprises: a flake matrix, a first metal oxide layer coated on the upper portion of the transparent matrix, an oxide layer containing MgO&#x2014;SiOcoated on the upper portion of the first metal oxide layer, and a second metal oxide layer coated on the upper portion of the oxide layer. In order to ensure humidity resistance and weather resistance required for a lustrous pigment paint for exterior materials, a cerium layer and an aluminum oxide layer are further coated. Properties such as high luminance, high chromaticity, and high gloss, which could not be achieved using conventional techniques, can be achieved and a pigment paint having a multi-colored pearl luster can be provided.
