photosensitive recording materials (col. 1, lines 9-30). Evans
teaches that tetrahydroquinolines were known as stabilizers for
lubricants (col. 1, lines 28-30). Evans states that “it has now
been found that dimeric, trimeric and tetrameric
tetrahydroquinoline derivatives are particularly suitable as
stabilisers for organic material” (col. 1, lines 31-34). The
disclosed organic materials include lubricants (col. 3, lines 17-
23; col. 7, lines 4-9). The tetrahydroquinoline derivatives,
when used as antioxidants for lubricants, can be used with other
antioxidants, some of the disclosed other antioxidants being
secondary diarylamines (col. 11, lines 3-10 and 19-24). Evans
does not disclose a composition which includes the prior art
dihydroquinolines and either lubricating oil or secondary
diarylamines.
Meier discloses lubricants containing N-substituted 1,2,3,4-
tetrahydroquinolines as antioxidants, and optionally containing
additional antioxidants which can be secondary diarylamines which
fall within the appellants’ claim 1 (col. 1, lines 8-15; col. 7,
lines 5-8; col. 8, lines 29-35). Meier does not disclose
dihydroquinolines.
