Abstract (en)

A specular product presenting a color of golden tone and possessing good resistance to discoloration is disclosed. The specular product comprises a metal base and electrodeposits of golden tone electroplated on the base metal. The electrodeposits comprises copper-zinc-nickel alloys having the Cu:Zn:Ni deposition ratio within the range of 70-85 : 15-25 : 1-10 and having a color described by the parameters of L*=80-95, a*=-5-0 and b*=15-25 as defined by the CIE-1976 (L*,a*,b*) color space indication.
