ABSTRACT:
Disclosed is a method for electroless metal deposition, which comprises steps of: forming, on the surface of a non-conductive body to be plated, a coating of a resin composition for the electroless metal deposition containing therein a polymer (A) having a chemical structure of at least one compound selected from the group consisting of the below-listed (a), and at least one compound selected from the group of the below-listed (b)1 and (b)2; applying a negative electrostatic voltage to the film coating of the resin composition at a temperature level above the glass transition point of said resin composition; thereafter removing the applied voltage at a temperature lower than the glass transition temperature; and successively carrying out the metal deposition steps inclusive of the catalyst imparting step and the activating step:
(a) a chemical structure, in which a part of hydrogen in the main chain of polymer is substituted with the halogen group or the nitrile group, and a chemical structure having a double bond at a portion held between the aromatic substituents in the main chain of the polymer; and
(b)1 a polymer (B) having a functional group which is capable of forming a metal salt; and
(b)2 a low molecular weight compound (C) having a functional group which is capable of forming a metal salt, and having complete miscibility with the polymer (A) to form one phase.
