The present invention relates to a method for forming a metal pattern on a pattern formation section set on a base material. In the present invention, a substrate provided with a fluorine-containing resin layer on a surface of the base material including the pattern formation section is used. The present inventive method for forming a metal pattern includes steps of: forming a functional group on the pattern formation section; and applying a metal ink including an amine compound and a fatty acid as protective agents to the base material surface to fix the metal particles on the pattern formation section. In the present invention, a fluorine-containing resin having a surface free energy measured by the Owens-Wendt method of 13 mN/m or more and 20 mN/m or less is applied as the fluorine-containing resin layer. Further, a metal ink including ethyl cellulose as an additive is applied as the metal ink.

The invention provides a dyeing solution for lithographic printing plates and a dyeing method for waterless lithographic printing plates that show stable plate inspection characteristics with little decrease in dye concentration and less dyeing unevenness even when used for bulk plate processing. The dyeing method for waterless lithographic printing plates is designed so that when used to dye an image area formed on a waterless lithographic printing plate with a dyeing solution containing an organic solvent, the relation of |β−α|<5 (cal/cm.sup.3).sup.1/2 is held wherein β is the SP value of the polymer compound included in the image area and α is the SP value of the organic solvent. The dyeing solution for lithographic printing plates contains (a) a dye, (b) a specific anionic surface active agent, and (c) an organic solvent containing at least one selected from ethers and alcohols.
