Appeal No. 1997-0195
Application 08/126,987
over the layer containing carbon black, a layer on the opposite side of the support from the
layer containing carbon black, or a layer in the photographic element remote from the silver
halide emulsion layer. Column 3, lines 7-13.
4. Harbison does not disclose that the photographic element comprises
chlorinated s-triazine hardeners or compounds containing cyano groups as recited in claim
1. Nor does Harbison disclose storing the element in a closed vessel at a constant
relative humidity as recited in claim 1.
5. Kadowaki discloses that the use of chlorinated s-triazine hardeners (i.e.,
cyanuricchloride type hardening agents: column 10, lines 39-43) in photographic materials
has a great disadvantage. Photographic materials containing chlorinated s-triazine
hardeners do not store well, and the sensitivity of the photographic material diminishes
with time. Column 1, line 67, through column 2, line 16. Kadowaki teaches that when
chlorinated s-triazine hardeners are used in silver halide photographic materials
comprising silver halide not sensitized with Kadowaki’s sensitizer of formulas (Ia) or (Ib) at
column 3, lines 21-68, the sensitivity of the photographic material decreases after one
month storage. Examples 8 and 9 in Table III at column 22.
6. Kadowaki discloses a photographic material comprising at least one silver
halide emulsion layer that includes silver halide having a silver chloride content of not less
than 25 molar% and silver halide sensitized with a compound of formula (Ia) and/or a
