摘要： PURPOSE: To obtain a tin, lead or tin-lead alloy plating bath giving homogeneous and dense plating at high speed, by adding cationic and nonionic surfactants each hving a specified structure and a leveling agent to a tin, lead or tin- lead alloy plating soln. contg. alkane sulfonic acid.
CONSTITUTION: A plating bath contg. alkanesulfonic acid, alkanolsulfonic acid and bivalent tin salt and/or lead salt is prepared. To the plating bath are added about 0.01W50g/l of ≥1 kind of cationic surfactant represented by formula I or IIsuch as lauryltrimethylammonium salt and/or ≥1 kind of nonionic surfactant represented by formula III such as styrenated phenol and about 0.01W30g/l leveling agent such as N-(3-hydroxybutylidene)-p-sulfanilic acid. The resulting plating bath does not contain hydroborofluoric acid which is unfavorable for pollution control. The bath can be used over a wide range of current density.

摘要： PURPOSE: To restore coloring treatment capacity of a coloring bath, in electrolytically coloring an Al material by an electrolytic coloring bath containing a metal salt, by pasing a superannuated coloring bath through strongly acidic cation exchange resin bed to which metal cation is adsorbed.
CONSTITUTION: A building member or the like made of Al or an Al alloy is subjected to anodic oxidation treatment by an acidic electrolytic coloring bath comprising an acid such as an alkane sulfonic acid, an alkanol sulfonic acid, an aryl sulfonic acid, a hydroxyaryl sulfonic acid or the like containing a metal salt of Sn, Ni, Cu, a noble metal or the like as a coloring agent to form a colored film. When Al is dissolved in said coloring bath to pollute the same and a content of the metal salt for coloring is consumed and reduced, the above described superannuated coloring bath is passed through a strongly acidic cation exchange resin bed to which the metal salt for coloring a absorbed. Al cation in said coloring bath is adsorbed and removed to said resin bed as well as metal ion in said resin bed is released and contained in said coloring bath and, thereby, coloring treatment capacity of said coloring bath is restored.
