Article and manufacturing method of article

A method of manufacturing an article, comprising

• adding a resin composition including a thermoplastic resin and metal-resin composite particles to an injection apparatus cylinder followed by melting/kneading to prepared a first mixture,
• injecting a gas into the first mixture to prepare a second mixture, and
• injection-molding the second mixture to manufacture an article,
• wherein the metal-resin composite particles comprise a metal deposition layer, a first coating layer positioned on one side of the metal deposition layer, and a second coating layer positioned on the other side of the metal deposition layer,
• the first coating layer and second coating layer comprises a thermosetting resin respectively, and
• the article comprises pores,
• the metal-resin composite particles have a flat surface, and wherein the flat surface of the metal-resin composite particles has an angle of about 0° to about 30° with reference to the surface of the article,
• the first coating layer and second coating layer include a thermosetting resin respectively, wherein the thermosetting resin comprises a silicone resin and wherein at least one of the first coating layer and the second coating layer further includes polyvinyl butyral (PVB),
• the thermoplastic resin comprises a polyalkyl(meth)acrylate resin, and
• the metal-resin composite particles are included in an amount of about 0.1 to about 2.0 parts by weight based on about 100 parts by weight of the thermoplastic resin.
