Abstract
Print pastes are thickened by a thickener concentrate containing about 5-50% by weight of a nonionic polyurethane having a molecular weight of at least 10,000 and at least 3 hydrophobic branching groups linked through hydrophilic polyether segments, a surfactant in an amount providing a thickener to surfactant weight ratio of about 1:0.01 to about 1:10, about 5-35% by weight of a non-aqueous organic diluent, and 0-65% by weight of water.
