Dispersions are prepared by mixing a solution of a polyamide with water containing a watersoluble copolymer having a K value of at least 90 containing 15-35% by wt. acrylic and/or methacrylic acid and up to 85% by wt. of acrylamide of which up to 40% by wt. may be replaced by methacrylamide. All or part of the solvent may subsequently be distilled off. The polymer may also contain up to 1% by wt. of the total monomers of N-methylolaorylamide and/or N-methylolmethacrylamide. Conventional dispersing agents may also be present.
