Appeal No. 1995-2781
Application No. 07/804,868
sensitive silver halide grains, a compound providing
a heat transferable magenta dye, and a hydrophilic
binder, a cyan dye producing layer containing light-
sensitive silver halide grains, a compound providing
a heat transferable cyan dye, and a hydrophilic
binder, and where said material contains a thermal
solvent for facilitating non-aqueous thermal dye
diffusion transfer, according to formula I,
wherein
(a) Z1, Z2, Z3, Z4, and Z5 are substituents, the
Hammett sigma parameters of Z2, Z3, and Z4 sum to
give a total, G, of at least -0.28 and less than
1.53;
(b) the calculated logP for I is greater than 3 and
less than 101 with the proviso that said heat
transferable yellow, magenta, and cyan dyes formed
upon reaction of said compounds with the oxidation
product of a primary amine developing agent transfer
at a temperature of from about 50°C to 200°C.
1. The § 103 rejection over Kohno
Claims 1-6, 9-11, 14-16, 33-38, 41-43 and 46-51 are
rejected under 35 U.S.C. § 103 over Kohno.
Kohno describes heat developable silver halide
photographic medium and the transfer of the image by heating
the composite of the receiving element and the exposed medium
