    摘要: The spread of printing paste when applied to textiles is inhibited by the inclusion of an "anti-wick agent" in the print paste. The "anti-wick agent" comprises a copolymer resulting from the polymerization of at least one monomer selected from the group consisting of methacrylic acid, acrylic acid, maleic acid and maleic anhydride with at least one monomer selected from the group consisting of acrylate esters and N-substituted acrylamides.
