1. A method for the decomposition of a metal into an inert substrate from a bath containing said metal, said metal comprising the steps of:

  • applying to said substrate a thin film of a thermally decomposable complex of palladium or platimum having the formulaeLmPdXn orLmPtXn whereinL is a ligand or an unsaturated organic group;

    Pd or Pt is palladium or platinum metal;

    X is a halide, an alkyl group or a bidentate ligand; and

    m is from 1 to 4 and n is from 0 to 3;

    exposing said substrate to which said complex has been applied to heat at a temperature of about 300°

    C and less to effect decomposition of said complex and to create a residue catalytic to a metal in an electroless bath solution; and

    depositing a metal from said electroless bath on said substrate in an area rendered catalytic by decomposition of said complex.
