ABSTRACT:
Metallic images of uniform quality can be formed on substrates having through-holes by a process using a positive type resist characterized by using as a coating solution for the substrate a solution of a photosensitive material of (a) at least one organic compound having at least one linkage of --M--M--M ).sub.n (M=Si, Ge or Sn; n=0, 1 or more) in the molecule or (b) a mixture of at least one organic compound (a) mentioned above and at least one photosensitizer, dissolved in a solvent such as a halogenated hydrocarbon, an aromatic hydrocarbon, a heterocyclic compound, or a mixture thereof, followed by irradiation with an actinic light through a photomask and electroless plating.
