Method for making metallic patterns |
abstract |
K-17800/=/MA 1977 Abstract of the Disclosure Method for making metallic patterns The present invention provides a method for making a metallic pattern on a substrate having a surface comprising bare metal in predetermined areas and metal coated by a resist in remaining areas which comprises (i) protecting the bare metal by coating with a film-forming resin, (ii) removing any film-forming resin from the resist, (iii) removing the resist from said remaining areas using a solvent which will not remove the film-forming resin, thereby exposing metal in said remaining areas, (iv) etching the metal exposed in (iii) using an etchant which does not remove the film-forming resin and (v) removing the film-forming resin with a suitable solvent. |
