Appeal No. 1998-0189
Application 08/196,933
We reverse rejections (1) through (6). In addition, we enter a new ground of
rejection under the provisions of 37 C.F.R. § 1.196(b), and raise other issues for the
examiner and the appellant to consider.
BACKGROUND
The claims are directed to a recording sheet that comprises a paper or a
transparent polymeric substrate and a coating thereon. The coating comprises an
active material, which includes 2-amino-pyrimidines. The claims require that the
recording sheet be suitable for receiving printed images, and that the coating be
suitable for receiving rapid drying images of an aqueous ink.
DISCUSSION
Rejections (1) through (5)
The following findings of fact are supported by a preponderance of the evidence.
1. Both Tachibana and Takeda describe light-sensitive materials that comprise a
support having thereon a light sensitive silver halide-containing layer.
2. Tachibana’s light sensitive layer comprises a silver halide emulsion layer that
can be stabilized by the compounds listed at column 10, lines 36-56, which include
pyrimidine compounds (column 10, lines 46-51). The silver halide emulsion layer
comprises silver halide, developing agents, inhibitors, and a hydrophilic colloid. The
developing agents and inhibitors enhance the developability of the silver halide
