The present disclosure provides dimeric fluorosurfactants related methods and ink-jet inks incorporating such fluorosurfactants. As such, an ink-jet ink can comprise 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 colorant.
