- Example 1 The color of the specimens surface-treated in Example 1, Example 2, Comparative Example 1 and Comparative Example 2 was visually evaluated.
- any three points A to C on the specimen prepared in Example 2 were selected, the color coordinates in the CIE color space were measured for the selected points, and the color coordinate deviations were determined from the measured color coordinates. .
- the color coordinate deviation ⁇ E * was derived using Equation 3 below.
- the surface-treated substrate according to the present invention includes the wavelength conversion layer and the color realized by the coating is maintained even after the top coat is formed. More specifically, before forming the wavelength conversion layer in Examples 1 and 2, the color implemented on the surface by the coating was red and green, respectively, and then the wavelength conversion layer and the top coat were sequentially formed on the coating. It was confirmed that the color of the surface does not change even. On the contrary, in Comparative Example 1 and Comparative Example 2, the colors implemented on the surface were red and green, respectively, before the top coat was formed, but when the top coat was formed on the coating, the color implemented on the surface was discolored. At this time, the color to be discolored changed to brown or black depending on the thickness of the top coat.
- the wavelength conversion layer When the wavelength conversion layer is formed between the film and the top coat as in the specimen of the embodiment, it means that the wavelength conversion layer minimizes refraction and scattering of the emitted light and prevents color discoloration by performing light reflection.
- the surface treated substrate according to the present invention has a uniform color. More specifically, the specimen of Example 2 comprising a wavelength conversion layer has an average color coordinate deviation of 0.14 ⁇ ⁇ L * ⁇ 0.34, 0.02 ⁇ ⁇ a * ⁇ 0.34 and 0.34 ⁇ ⁇ b * ⁇ for any three points present on the specimen. It was found that 0.40 and 0.424 ⁇ ⁇ E * ⁇ 0.578. This means that the color of the color-treated magnesium according to the present invention is uniformly colored.
- the surface-treated substrate according to the present invention may include a film having a uniform thickness on the metal matrix to implement color uniformly.
- a film having a uniform thickness on the metal matrix to implement color uniformly.
- the surface-treated substrate according to the present invention may not only improve the corrosion resistance by including a film having a uniform thickness on the metal matrix, but also uniformly implement color on the surface.
- by sequentially including the wavelength conversion layer and the top coat on the coating can improve the scratch resistance and durability of the substrate without discoloration of the color implemented by the coating, so that the exterior of the building material, automotive interior, especially magnesium It can be usefully used in the field of electrical and electronic component materials such as mobile phone case parts.
