摘要： The present invention provides a tin-containing plating bath comprising: (a) a soluble stannous salt, or a mixture of a soluble stannous salt and at least one soluble salt selected from the group consisting of copper salts, bismuth salts, silver salts, indium salts, zinc salts, nickel salts, cobalt salts and antimony salts; and (b) at least one aliphatic sulfonic acid selected from the group consisting of alkanesulfonic acids and alkanolsulfonic acids, the aliphatic sulfonic acid being a purified aliphatic sulfonic acid in which the total amount of sulfur-containing compounds as impurities consisting of compound(s) containing one or more sulfur atoms with an oxidation number of +4 or less in the molecule and compound(s) containing one or more sulfur atoms and one or more chlorine atoms in the molecule is a minute amount or less. A tin or tin alloy plating film with excellent reflowability, film appearance, etc. can be formed by the use of this plating bath.

摘要： Provided is an electrosilver plating bath yielding a semiglossy to glossy appearance across a wide current density range without the use of a cyan compound, and a plating method using the electrosilver plating bath. An electrosilver plating fluid that is an aqueous solution containing (A) at least one soluble silver compound, (B) at least one benzoic acid derivative or a salt of the derivative, and (C) at least one acid and/or complexing agent, wherein the benzoic acid derivative is expressed by the following general formula (m is 1, 2, 3, 4 or 5; Ra is a carboxyl group; individual instances of Rb are selected independently from an aldehyde group, a carboxyl group, an amino group, a hydroxyl group, or a sulfonic acid group; individual instances of Rc are independently oxygen or any substituent; and one or more oxygen or CH 2 may be introduced into the bond between Ra or Rb and a benzene ring.
