Appeal No. 95-4066
Application 07/963,189
the examiner has failed to provide, as was his burden,
evidence establishing that the skilled routineer would have
been motivated to substitute for gold of the admitted prior
art configuration the silver-copper alloy reflector layer of
Tomie as modified by Kobayashi, Takahashi and Shindo.
Secondly, and more significantly, claims 1, 4, 6, 10, 12,
13, 15, 17 and 20 require a silver-palladium alloy and none of
Tomie, Kobayashi or Takahashi is directed to silver-palladium
alloys. Tomie is directed to silver-copper alloys. Kobayashi
is directed to aluminum layers or aluminum alloys covered with
protective layers of tantalum. While Kobayashi does disclose
palladium as a useful metal for alloying metal reflector
layers, the metal to which it is suggested that palladium may
be added is aluminum. Similarly, Takahashi alloys aluminum
with nickel, palladium, platinum, chromium or molybdenum.
Shindo recognizes a problem with the adherence of the
organic dye recording layer to the metal reflector layer and
resolves the problem by further including an organic
heterocyclic compound intermediate layer between the recording
layer and the metal reflector layer. While Shindo does
recognize, in the broadest sense, that alloys of silver and
