Appeal No. 2002-0178
Application 09/385,909
APPENDIX
1. A process for the preparation of an ink which comprises
mixing an ink vehicle, a colorant and a latex generated by the
polymerization of a mixture of olefinic monomers, wherein at
least one of said olefinic monomers is an ionic sulfonate monomer
and which polymerization is accomplished in the presence of an
anionic surfactant, and a nonionic surfactant.
2. A process in accordance with claim 1 wherein said latex
is generated from a mixture of from about 2 to about 10 monomers.
3. A process in accordance with claim 1 wherein said latex
is generated from a mixture of from about 2 to about 4 monomers.
4. A process in accordance with claim 1 wherein said
olefinic monomer is a styrene acrylate, a styrene methacrylate, a
methacrylate, or an acrylate.
5. A process in accordance with claim 1 wherein said
olefinic monomers are comprised of said ionic sulfonate monomer,
an alkyl acrylate, and an alkyl methacrylate.
6. A process in accordance with claim 1 wherein said
olefinic monomers are comprised of said (1) ionic sulfonate
monomer, and (2) an alkyl acrylate, an alkyl methacrylate, a
benzyl methacrylate, an acrylonitrile, a styrene functional
monomer, or an acid olefinic monomer.
7. A process in accordance with claim 1 wherein subsequent
to polymerization there results a terpolymer, or a copolymer.
8. A process in accordance with claim 1 wherein the ionic
sulfonate monomer is of the formula
CH2 = CR(R')mSO3X
wherein R is hydrogen or alkyl, R' is alkylene, or –CO-R2 wherein
R2 is amino substituted with alkyl or hydrogen, or R2 is (CH2)n-0,
wherein n represents a number of from about 0 to about 5; X is
hydrogen, or a monovalent cation and m represents the number of
segments of R', and wherein the ionic sulfonate monomer is
selected in an amount of from about 0.5 to about 15 weight
