Appellants' claimed invention is directed to an ink for
an ink jet printing process. The ink comprises colored
particles dispersed in an emulsifiable polymer resin. Also,
the ink has the recited surface tension and viscosity.
Appellants submit the following two groups of claims at
page 4 of the principal brief: (I) claims 1-13 and 16; and
(II) claim 20. Accordingly, claims 2-13 and 16 stand or fall
together with claim 1.
