Patent ID: 7530683

Claim:
A fixer fluid comprising a cationic fixing agent, an oxysilyl groups-containing species and a vehicle, wherein the fixer fluid is substantially colorless, has a surface tension in the range of about 20 dyne/cm to about 70 dyne/cm at 25° C., and a viscosity as high as 30 cP at 25° C., and wherein the oxysilyl groups-containing species is a molecule containing at least two reactive hydroxysilyl, alkoxysilyl, aryloxysilyl and/or acyloxysilyl moieties of the formula selected from the group consisting of formulas (IA) and (IB): wherein each R is Individually a hydrogen, an alkyl group, an aryl group or an acyl group; s is 1, 2 or 3; and t is 1or 2, provided that if s or t is 1, then the molecule contains at least two such moieties.
