COLOR-TREATED BASE MATERIAL AND BASE MATERIAL COLOR TREATMENT METHOD THEREFOR

摘要

The present invention relates to a color-treated base material and a base material color treatment method therefor. The base material is capable of improving the homogeneity and corrosion resistance of the surface of the base material and realizing a uniform color in a short period of time. Accordingly, the color-treated base material can be usefully used in the fields of building exterior materials, automobile interiors, and particularly electrical and electronic component materials, such as mobile phone case components, in which a magnesium material is used.
