The present disclosure describes phosphonium-containing polyurethane compositions, coating compositions, and coated fabric media. In one example, a phosphonium-containing polyurethane composition can include an aqueous liquid vehicle and polyurethane particles. The polyurethane particles can include a polyurethane polymer devoid of end cap groups. The polyurethane polymer can include a polyurethane backbone having a polymerized diamine chain extender forming a portion of the backbone. The polyurethane polymer can also include side chain groups along the polyurethane backbone. The side chain groups can collectively include aliphatic phosphonium salts and polyalkylene oxide groups.

A phosphonium-containing polyurethane composition can include an aqueous liquid vehicle including water, organic co-solvent, and surfactant, and polyurethane particles including a polyurethane polymer with a polyurethane backbone. The polyurethane polymer can have pendant side chain groups along the polyurethane backbone as well as end cap groups terminating the polyurethane polymer. The pendant side chain groups and the end cap groups can collectively include aliphatic phosphonium salts and polyalkylene oxides.

A fixer fluid can include a fixer vehicle with water, an NH-type or N-alkylated lactam co-solvent, and a phosphate ester surfactant. The fixer fluid can further include from 0.5 wt % to 12 wt % an azetidinium-containing polyamine polymer dispersed in the fixer vehicle.

A printing method includes selecting a dye sublimation ink, having: a disperse dye colorant dispersion; a primary solvent selected from the group consisting of glycerol, ethoxylated glycerol, 2-methyl-1,3-propanediol, dipropylene glycol, and combinations thereof; a surfactant selected from the group consisting of nonionic surfactants, anionic surfactants, and combinations thereof; an additive selected from the group consisting of a buffer, a biocide, a chelating agent, and combinations thereof; and a balance of water. An operating energy that includes a margin over a turn-on energy (TOE) for a thermal inkjet printhead is applied to a heating resistor of the printhead, wherein the margin ranges from about 10% to about 25% over the TOE. The dye sublimation ink is printed from the thermal inkjet printhead i) directly onto a textile substrate, or ii) onto a transfer medium to form an image thereon; and the image is transferred onto the textile substrate.
