FIXER FLUIDS

摘要

The present disclosure provides fixer fluid compositions and related systems and methods. In one example, a fixer fluid can comprise a liquid vehicle, a surfactant, and a cationic polymer. The liquid vehicle can include water and co-solvent having a boiling point from 160°C to 250°C, the co-solvent present in the fixer fluid in an amount of 1 wt% to 40 wt%. The surfactant can be present in the fixer fluid in an amount of 0.1 wt% to 10 wt%. The cationic polymer can be present in the fixer fluid in an amount of 0.1 wt% to 25 wt%. The fixer fluid can be formulated for printing on non-porous media and does not include more than 5 wt% volatile co-solvent and more than 3 wt% non-volatile co-solvent.
