Abstract: PROBLEM TO BE SOLVED: To plate thin having high reflecting property on a substrate under fast electroplating conditions by incorporating stannous sulfonate and sulfonic acid to control the bath to specified pH, adding a specified concentration of a reaction product of polyalkylene glycol and phenolphthalein. SOLUTION: Sulfonic acid is mixed by about 10 to 30 g/l in an aq.soln. containing stannous sulfonate by preferably about 10 to 100 g/l concentration as metallic tin to control the pH of the liquid to about
