The present invention comprises: a metal base material providing step; a light diffusion layer forming composition application step; and a press molding step. A light diffusion layer forming composition relates to the method for preparing a door frame molding, wherein a door frame molding comprises: a transparent polymer resin, a light diffusion agent, and an organic solvent. The door frame molding manufactured by the manufacturing method has excellent light diffusivity and light reflectivity, reduces manufacturing costs as compared with the molding made of an existing light diffusing SUS material and the aluminum die-casting molding to have excellent economic efficiency, and maximizes own diffused reflection of a light reflecting metal material to have aesthetical appearance. |
