METHOD FOR MANUFACTURING PRODUCT WITH BRIGHT SURFACE

摘要

Provided is a method of manufacturing a bright surface product having good surface brightness and excellent rust and detachment resistance which can be produced in a large scale at low cost. The method comprises: a step of performing electroless plating to form a first metal film 23 on a base coat layer 22 formed on a substrate 21; a step of performing electrolytic plating to form a second metal film 24 thereon so that the bonding strength between each film of a multi-layered metal film comprising the first metal film 23 and the second film 24 is higher than the bonding strength between the base coat layer 22 and the first metal layer 23; a step of integrally and discontinuously segmentalizing the multi-layered metal film with cracks 26 by utilizing the difference in internal stress between the substrate 21 and the multi-layered metal film to form an island-like metal film comprising a collection of fine multi-layered metal regions 25 with island-like structures and having an appearance of an integrated bright surface; and a step of forming a translucent top coat layer to cover the fine multi-layered metal regions 25 of the island-like metal film and enter into the cracks 26 to make contact with the base coat layer 22.
