The present invention relates to new carboxy-functional polyester and diester derivatives preparable by ring-opening reaction of (A) at least one anhydride of the formula (I) where R&#x2550;H, Cto Calkyl, or Cto Calkenyl with (B) at least one hydroxy-functional component, where (B1) the polyester derivatives are prepared using at least one linear hydroxy-functional polyester prepared using 7 to 95 mol %, based on the total amount of the monomers used in preparing the polyester (B1), of at least one difunctional monomer (b1) with aliphatic groups with 12 to 70 carbon atoms between the functional groups, and (B2) the diester derivatives are prepared using at least one dihydroxy-functional component which has an aliphatic group with 12 to 70 carbon atoms between the hydroxyl groups. The present invention further relates to aqueous compositions comprising at least one such polyester derivative and/or diester derivative, and water. The present invention relates, moreover, to the use of the polyester and/or diester derivatives for producing liquid-crystalline phases.
