A method for treating the surface of a substrate with a surface treatment composition, wherein the surface treatment composition comprises a liquid medium containing a complexing agent as a metal deposition preventive, the complexing agent comprising at least one member selected from the following Group A complexing agents and at least one member selected from the group consisting of the following Groups B1 to B6 complexing agents:n Group A: complexing agents having an aromatic hydrocarbon ring in the molecular structure thereof and at least one of an OH group and/or an O - group bonded directly to a carbon atom constituting the ring; Group B1: complexing agents having at least one nitrogen atom as a donor atom in the molecular structure thereof; Group B2: complexing agents having at least one atom selected from halogen, sulfur and carbon atoms as a donor atom in the molecular structure thereof; Group B3: complexing agents having at least one oxygen atom as a donor atom in the molecular structure thereof, but not having a carbonyl group and a carboxyl group and not having any one of nitrogen, halogen, sulfur and carbon atoms as a donor atom; Group B4: carboxylic acid type complexing agents having at least one carboxyl group in the molecular structure thereof, but not having any one of nitrogen, halogen, sulfur and carbon atoms as a donor atom and not having a carbonyl group and a hydroxyl group; Group B5: hydroxymono- or di-carboxylic acid type complexing agents having at most 4 hydroxyl groups in the molecular structure thereof, but not having any one of nitrogen, halogen, sulfur and carbon atoms as a donor atom and not having a carbonyl group; and Group B6: complexing agents having at least one carbonyl group in the molecular structure thereof. |
