成樹脂成型品の製造方法。8. An antistatic coating material is applied to a surface of a first mold forming material, and the antistatic coating material is joined to the first mold forming material while the surface of the antistatic coating material is exposed to air. Partially polymerize from the surface side to form an antistatic coating whose surface does not have sufficient hardness, apply a scratch-resistant coating material to the surface of the antistatic coating, and expose the surface of the scratch-resistant coating material to air The anti-static coating is polymerized in the above state and the scratch-resistant coating raw material is partially polymerized from the bonding surface side with the anti-static coating to form a first scratch-resistant coating whose surface does not have sufficient hardness. An antistatic coating material is applied to the surface of the second mold forming material, and the antistatic coating material is exposed to the air with the surface of the antistatic coating material exposed to air. Partially polymerized and surface has sufficient hardness Forming an antistatic coating, applying a scratch-resistant coating material to the surface of the antistatic coating, polymerizing the antistatic coating while exposing the surface of the scratch-resistant coating material to air, and applying the scratch resistance The coating material is partially polymerized from the bonding surface side with the antistatic coating to form a second scratch-resistant coating whose surface does not have sufficient hardness, so that the two scratch-resistant coatings are located inside the mold. The first mold-forming material and the second mold-forming material are arranged so as to have a space by a gasket, and a base resin material is filled inside a mold composed of the abrasion-resistant coating and the gasket. The synthetic resin molded article is formed by swelling the scratch-resistant coating with the base resin material and sufficiently polymerizing and integrating the base resin material and the scratch-resistant coating by radical polymerization. And a method for producing a synthetic resin molded product.
