Abstract

See full text

A method of manufacturing a bright surface product comprises a step of performing electroless plating to form a first metal film on a base coat layer formed on a substrate, a step of performing electrolytic plating to form a second metal film thereon so that the bonding strength between each film of a multi-layered metal film comprising the first metal film and the second film is higher than the bonding strength between the base coat layer and the first metal layer, a step of integrally and discontinuously segmentalizing the multi-layered metal film with cracks to form an island-like metal film comprising a collection of fine multi-layered metal regions with island-like structures; and a step of forming a translucent top coat layer to cover the fine multi-layered metal regions of the island-like metal film and enter into the cracks to make contact with the base coat layer.
