<p>A method for coloring a metal thin plate provided in a key-pad for a personal mobile terminal includes a first process of coating a first coating agent on a surface of the metal thin plate by using at least one of a physical vapor deposition and a chemical vapor deposition, the first coating agent having a predetermined saturation; and a second process of coating secondarily a second coating agent on the primarily coated surface of the metal thin plate by using at least one of the physical vapor deposition and the chemical vapor deposition, the second coating agent having predetermined saturation with a refractive index that is different from a refractive index of the first coating agent. A key-pad for a personal mobile terminal includes a metal thin plate comprising plural coating layers formed thereon to present colors, the coating layers having pre-determined saturation and different refractive index of light; and a pad mounted on a lower surface of the metal thin plate, wherein plural buttons and significant marks formed at the buttons are formed on an upper surface of the metal thin plate as one body, further wherein plural switching projections are formed on a lower surface of the pad.</p> |
