Application 08/126,987
compound of formula (Ib). Kadowaki further discloses that the emulsion layer is hardened
with a chlorinated s-triazine compound of formula (II) and/or a chlorinated s-triazine
compound of formula (III). Kadowaki, column 3, line 10, through column 4, line 37.
Kadowaki discloses that the silver halide photographic material exerts good storage
property with time or “a lower change in sensitivity after storage.” Column 3, line 2-5, and
Examples 5, 6, and 10 through 12 in Table III at column 22.
7. The Ishikawa abstract describes storing a photographic element at a relative
humidity of at least 55% in a hermetically sealed vessel. Appellants state that Ishikawa
reduces fog in light-sensitive elements during storage in a closed vessel by decreasing the
humidity in the vessel. Specification, page 2, lines 1-5.
8. In setting forth the rejection under 35 U.S.C. § 103, the examiner characterizes
Kadowaki as teaching that triazine hardeners may be used in the presence of a palladium
compound. The examiner relies on the description of Kadowaki at column 13, lines 31-37,
to support that position. Answer, page 4, lines 18-21. Kadowaki at column 13, lines 31-
37, teaches that the silver halide emulsion can be sensitized with a palladium metal
sensitizing agent. The examiner concludes that “[i]t would have been obvious to store a
photographic element at a constant relative humidity in a closed vessel as taught by
Ishikawa . . . wherein the element comprises a palladium compound as hydrogen cyanide
scavenger as taught by Harbison . . . since both the constant humidity and palladium
