Abstract

The present disclosure provides ink-jet inks incorporating dimeric fluorosurfactants. As such, an ink-jet ink can include a liquid vehicle; a non-ionic fluorosurfactant dimer having the structure CF₃(CF₂)_x(CH₂)_y(CR₂CR₂O)_z-A-(OCR₂CR₂)_a(CH₂)_b(CF₂)_cCF₃, where R is independently H or methyl, A is a bridging unit containing aliphatic or aromatic functionality, x is 3 to 18, y is 0 to 8, z is 0 to 100, a is 0 to 100, b is 0 to 8, and c is 3 to 18; and a polymer.

Claims

1. An ink-jet ink, comprising:

a liquid vehicle;

a non-ionic fluorosurfactant dimer having the structure CF₃(CF₂)_x(CH₂)_y(CR₂CR₂O)_z-A-(OCR₂CR₂)_a(CH₂)_b(CF₂)_cCF₃, where R is independently H or methyl, A is a bridging unit containing aliphatic or aromatic functionality, x is 3 to 18, y is 0 to 8, z is 0 to 100, a is 0 to 100, b is 0 to 8, and c is 3 to 18; and

a cationic polymer.

2. The ink-jet ink of claim 1, wherein x and c are independently 3 to 5, y and b are independently 0 to 4, and z and a are independently 0 to 25.

3. The ink-jet ink of claim 1, wherein the cationic polymer is a latex polymer.

4. The ink jet ink of claim 1, wherein the non-ionic fluorosurfactant dimer is present in the ink-jet ink at a concentration from 0.01 wt % to 5 wt %.

5. The ink jet ink of claim 1, wherein the non-ionic fluorosurfactant dimer is selected from the group consisting of a dimer with a single bridging group having the structure BAB;

a blend of two dimers with multiple bridging groups having the structure;

BAB+BA′

B;

a heterodimer with multiple monomer groups having the structure;

BAB′
