Abstract
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—SiO2 coated 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.
