Appeal No. 95-3353 Page 6
Application No. 07/855,799
Aotani is concerned with furnishing a "highly sensitive
light-sensitive composition containing a sensitizer which does
not crystallize in the light sensitive layer during
preservation." The composition is taught to be "useful for
light-sensitive layers of ... printing plates, photoresists,
etc." (column 1, lines 12-15). Aotani suggests selecting a
polymer "having photo-crosslinkable unsaturated bonds which
can be sensitized by the sensitizers of this invention..."
(column 6, lines 15-21). Among a variety of polymers
disclosed by patentees as useful with the sensitizer are
polymers containing azido group(s) such as those disclosed at
columns 6-8 of the patent. Aotani indicates that a binder,
plasticizer, and a dye or pigment may be additionally employed
in preparing the light-sensitive composition (column 8, lines
52-61). Carbon black is included in a disclosed list of
materials from which the dye or pigment may be selected
(column 9, lines 16-20).
The examiner acknowledges that Vandenberg does not
disclose the use of polyetherazides for forming an imageable
element as claimed by appellant (answer, page 3). Moreover,
the examiner acknowledges that Aotani does not disclose the
