fast to light and there is thermal instability in magenta couplers when stored in the dark.
See column 1, lines 56-58. We find that the magenta layers to which the stabilizers of
Rody ‘271 are added contain pyrazolone couplers. See column 20, lines 62 to column
21, line 65. Moreover, we find that the pyrazoline group disclosed by Rody ‘271
includes pyrazolone compounds that fall within the scope of the claimed subject matter
such that when R is aryl, Q’ is a group bonded to the pyrazole ring via O, and R is16 17
alkyl, pyrazolone compounds are present which are within the scope of the claimed
subject matter. Id.
Rody ‘665 similarly discloses tetrahydrothiopyran compounds having the requisite
sulfide, sulfoxy, or sulfone moieties required by the claimed subject matter. See Abstract
and column 1, lines 5-40. These compounds function as stabilizers for color
photography recording materials. See column 1, lines 6-7, column 11, lines 62-66 and
column 12, lines 15-17. The proportion of stabilizer added is disclosed at column 12,
lines 30-34. We find that the addition of the aforesaid stabilizers to magenta couplers is
disclosed at
column 16, line 62, to column 18, line 48. The magenta couplers disclosed include 1-
aryl-5-pyrazolones. See column 16, lines 62-63. For the same reasons discussed supra,
with respect to Rody ‘271, the magenta couplers disclosed includes pyrazolone couplers
within the scope of the couplers of the claimed subject matter. Id.
