Appeal No. 1998-3281
Application 08/650,500
THE INVENTION
The appealed subject matter is directed to a "process" for
placing in an ink jet apparatus an ink composition comprising
water, a colorant and a polymer bearing both hydrophobic groups
and hydrophilic groups.
Independent claim 22 is believed to be adequately
representative of the appealed subject matter and is reproduced
below for a more facile understanding of appellants' invention.
Claim 22. A process which comprises incorporating into
an ink jet printing apparatus an ink composition which
comprises water, a colorant, and a polymer selected
from (a) those of the general formula
wherein R is an organic group having at least two
carbon atoms, C is a hydrophobic saturated alkyl group
having at least about 6 carbon atoms bonded in a linear
chain, B is a hydrophilic group containing at least
about 9 atoms bonded in a linear chain, and n is an
integer representing the number of repeating monomer
units; or (b) those of the general formula
