Abstract:
1. A coating method of a housing for a portable electronic device, comprising: providing a metallic base; submerging the metallic base in a phosphate solution, thereby forming a chemical plating layer on the metallic base; coating a primer coating on the chemical plating layer and drying the primer coating, thereby forming a primer layer; coating a color coating on the primer layer and drying the color coating, thereby forming a color coating layer, wherein the color coating layer comprises acrylic resin, polyester resin, epoxy resin, amino resin, acrylate copolymer, propylene glycol methyl ether acetate, butyl ester, and pigments dispersed therein; coating a metallic luster coating on the color coating layer and drying the metallic luster coating, thereby forming a metallic luster layer, wherein the metallic luster layer comprises acrylic resin, polyester resin, epoxy resin, amino resin, acrylate copolymer, propylene glycol methyl ether acetate, butyl ester, pigments and aluminum oxide powder dispersed therein; laser irradiating predetermined regions of the metallic luster layer, thereby defining a pattern extending through the metallic luster layer for exposing the color coating layer; and coating a transparent coating on the metallic luster layer and drying the transparent coating, thereby forming a transparent protection layer on the metallic luster layer for protecting the metallic luster layer from abrasion.
