Application No. 09/794,362
specified tabular silver halide grains and a tellurium sensitizer
as claimed. Appellant states that “[t]he claims all stand
together for the purposes of this appeal” (brief, page 6).
Accordingly, we select claim 1 as the representative claim on
which we shall decide this appeal. Claim 1 is reproduced below.
1. A silver halide color photographic light-sensitive
material comprising, coated on a support, a photographic
structural layer that comprises at least one photographic
light-sensitive layer containing a light-sensitive silver
halide, a compound that forms a dye by a coupling reaction
with a oxidized product of a developing agent, and a binder,
wherein at least one photographic light-sensitive layer
of the light-sensitive material contains a silver halide
emulsion that comprises tabular silver halide grains having
principal faces composed of (lll) planes, an average
equivalent circle diameter of a least 0.70 µm, and an
average thickness of less that 0.20 µm, and the silver
halide of the emulsion is chemically sensitized by a
tellurium sensitizer,
wherein the tellurium sensitizer is a compound of formula
(III)
wherein, R31 and R32 each represent -(C=Y’)-R33; R33 represents
NR34(R35); Y’ represents an oxygen atom; R34 and R35 each represent
a hydrogen atom, an aliphatic group, an aromatic group, or a
heterocylic group and may bond together to form a ring; and n
denotes 1 or 2.
