A fixer composition includes a polyamine; a phosphate ester surfactant; a co-solvent; and a balance of water. The polyamine is selected from the group consisting of an azetidinium-containing polyamine, an epoxide-containing polyamine, and combinations thereof. The co-solvent contains two hydroxyl groups and an aliphatic chain between the two hydroxyl groups, the aliphatic chain containing three carbon atoms. The fixer composition may be used in combination with an inkjet ink and may be included in a fluid set and/or a textile printing kit.
