Appeal No. 1999-2760
Application 08/773,304
simply listed by Harmer at col. 8, lines 52 and 53, as one of
the ethylenically unsaturated monomers usable in the make coat
precursor; we do not find any disclosure in Harmer which would
have suggested to one of ordinary skill that “it is known to
use acryloxy for better curing,” as the examiner states, and
certainly no teaching or suggestion that a urea-aldehyde/EVA
system as disclosed by Engen would have better curing or be
improved in any other way if an acryloxy group-containing
compound were added thereto.
As for Harmer’s disclosure of a photosensitizer, the
reference states that photosensitizers may be included “in the
polymerizable compositions” (col. 16, lines 49 to 51), i.e.,
in the polymerizable compositions disclosed by Harmer.
However, since the polymerizable compositions disclosed by
Harmer are not of the same type as the urea-aldehyde/EVA
binder precursor composition disclosed by Engen, we do not
consider that Harmer would have taught one of ordinary skill
to include a photosensitizer in the Engen precursor. In other
words, given the differences between the polymer systems
disclosed in the two references, there would have been no
