Abstract

Provided is a resin article produced by melt processing and having layers formed by a layer-separation. having a layer-separated structure. The resin article may include a first resin layer and a second resin layer formed on the first resin layer. Also, the component of the first resin layer is detected on a surface of the second resin layer by infrared spectrometer. The resin article may have improved mechanical and surface characteristics. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.
