applied to the surface of the heat-sensitive layer, and 3)
heat is applied to cause a reaction to take place between the
pigment and the metal ions to form a chelate dye (pages 5 and
11). The pigment has an azo group linking a 3-hydroxy-
pyridine nucleus to a phenyl nucleus which can have an alkoxy
substituent at its 2-position (page 5).
Bailey and Komamura ‘422 disclose methods for producing a
photographic transfer image wherein 1) an imagewise-exposed
photographic element is treated with an alkaline processing
composition in the presence of a silver halide developing
agent to develop the exposed area of each of the silver halide
emulsion
layers, 2) a dye-releasing compound releases a diffusible azo
dye imagewise as a function of the development of each of the
silver halide emulsion layers, and 3) at least a portion of
the imagewise distribution of the azo dye diffuses to a dye
image-receiving layer to form a metal-complexed azo dye
transfer image (Bailey, col. 13, lines 13-26; Komamura ‘422,
col. 10, lines 3-26). The azo dye can have an alkoxy group at
the 2-position of a phenyl ring (Bailey, col. 2, lines 1-52;
-5-5
