Abstract

Claims (26)

1. A formulation for an ink fixer fluid, comprising:

at least one surfactant of Formula I,

wherein R 1 and R 2 may be the same or different, and may be selected from the group consisting of hydrogen and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;

n is an integer from 2 to 5 (including 2 and 5);

m is an integer from 9 to 20 (including 9 and 20) which denotes a linear alkyl chain;

the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;

an optional counterion associated with the compound which, if present, is selected from the group consisting of chloride, bromide, iodide, and hydroxide;

an ink fixer agent; and

water.

2. The formulation of claim 1 , wherein the fixer agent is a metal carboxylate.

3. The formulation of claim 1 , further comprising a humectant.
