Abstract
Water-soluble cross-linked polyamides are produced by reacting (B) a cross-linking agent with (A) the product of reacting (A.sub.1) a dicarboxylic acid and (A.sub.2) a polyamine, provided that at least one of (A.sub.1) (A.sub.2) and (B) contains an aromatic moiety or that the product of reacting (B) with (A) is further reacted with a compound containing an aromatic moiety.
