in order, a light transmitting substrate, a recording layer
containing a dye, and a light reflecting layer (col. 11,
lines 25-28). Preferably, the real part of the complex
refractive index (N) of the unwritten recording layer measured
with a 780 nm light source is not less than 1.8 and the
imaginary part (k) is not greater than 0.15 (col. 11, lines
33-36). The dye is a metal complex of a tridentate azo dye
ligand containing on one side of the azo linkage an
aminohydroxypyridine group, and on the other side an aromatic
ring including an electron withdrawing substituent (col. 2,
lines 32-36). The dye differs from appellants’ dye in that it
has an oxygen atom attached to the phenyl ring at the 2-
position (col. 3, lines 26-30) whereas, at this position,
appellants’ dye has an alkoxy group.
Komamura ‘092 discloses a method for forming an image by
laminating a layer of a heat-sensitive transfer material on an
image-receiving material, wherein 1) the heat-sensitive layer
contains a chelating pigment, 2) metal ions are present in
either the image-receiving material or in a heat-fusible layer
