Abstract:
A method of providing a metal pattern on a glass substrate by an electroless process, said method comprising applying an aqueous solution of a silane to the surface of a glass substrate to thereby provide said substrate with a silane layer, providing a patterned mask on said silane layer, exposing said masked silane layer to UV radiation while subjected to ozone to thereby remove portions of the silane layer and expose the glass substrate in the irradiated portions, removing said mask, bringing said substrate into contact with a Pd sol, stabilized with a water-soluble polymer and having, as its sole metal, Pd, to thereby activate the remaining portions of the silane layer only and then bringing said substrate into contact with an electroless metallization bath to thereby form a metal pattern on glass.
