양호한 표면 광휘성을 가지며, 방청성, 내박리성이 우수한 동시에, 저비용으로 대량생산 할 수 있는 표면 광휘품의 제조방법을 제공한다. 기재(21)의 베이스 코트층(22)상에 무전해도금으로 제1 금속막(23)을 형성하는 공정과, 그 위에 전해도금으로 제2 금속막(24)를 형성하고, 베이스 코트층(22)과 제1 금속막(23)과의 결합력보다, 제1, 제2 금속막(23,24)으로 구성되는 복층 금속막의 각 막 상호간의 결합력이 높아지도록 하는 공정과, 기재(21)와 복층 금속막과의 내부 응력차에 의해 복층 금속막을 일체적으로 크랙(26)에 의해 불연속으로 분할하여, 섬상(island-shaped) 구조의 미세 복층 금속영역(25)의 집합체로 이루어지며 일체적인 광휘면의 시인성(視認性)을 가지는 섬상 금속막을 형성하는 공정과, 미세 복층 금속영역(25)을 피복하는 한편 크랙(26)에 침투하여 베이스 코트층(22)과 접촉하도록 투광성의 탑 코트층(27)을 형성하는 공정, 을 구비한다.

    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.
