Silica-coated deposit layer formed by plating

Abstract

Improved plating is provided. The present invention provides a plated product which comprises a base, a deposit layer formed by plating on a surface of the base, and a silica-compound-containing coating layer formed on the surface of the deposit layer. The coating layer has a thickness of 0.1-100 μm, preferably 0.1-20 μm, more preferably 0.1-10 μm, even more preferably 0.1-5 μm. The coating layer may contain a dye and/or a pigment.

1 . A plated product comprising:
 a substrate made of resin;   a plating layer formed on a surface of the substrate; and   a coating layer comprising a silica compound, which is formed on a surface of the plating layer.   
     
     
         2 . The plated product of  claim 1 , wherein a thickness of the coating layer is 0.1 to 20 μm. 
     
     
         3 . The plated product of  claim 1 , wherein a thickness of the coating layer is 0.1 to 10 μm. 
     
     
         4 . The plated product of  claim 1 , wherein a thickness of the coating layer is 0.1 to 5 μm. 
     
     
         5 . The plated product of  claim 1 , wherein the coating layer comprises at least one of a dye and a pigment. 
     
     
         6 . The plated product of  claim 1 , wherein the coating layer comprises an added resin. 
     
     
         7 . The plated product of  claim 1 , which is for a vehicle. 
     
     
         8 . A method of manufacturing a plated product comprising
 a step of forming a plating layer on a surface of a substrate made of resin; and   a step of applying a coating agent comprising a silica compound to a surface of the plating layer to form a coating layer.   
     
     
         9 . A method of manufacturing of  claim 8 , comprising a step of carrying out plasma treatment, acid treatment, or alkali treatment to a formed plating layer before the step of forming a coating layer. 
     
     
         10 . The method of manufacturing of  claim 8 , wherein a thickness of the coating layer is 0.1 to 20 μm. 
     
     
         11 . The method of manufacturing of  claim 8 , wherein a thickness of the coating layer is 0.1 to 10 μm. 
     
     
         12 . The method of manufacturing of  claim 8 , wherein a thickness of the coating layer is 0.1 to 5 μm. 
     
     
         13 . The method manufacturing of  claim 8 , wherein the coating agent comprises an added resin. 
     
     
         14 . The method of manufacturing of  claim 8 , wherein the product is a product for a vehicle or an electronic product for a household.
