Abstract

Compounds having the structure ##STR1## wherein (Z)--COO is the residue of an iodinated aromatic acid; M is H, a cation, --CH.sub.2 CH.sub.2 O--.sub.m H, and --CH.sub.2 CH(OH)O--.sub.p H; m is an integer from 1 to 150; p is an integer from 1 to 50; and L is one or more divalent linking groups selected from alkylene, cycloalkylene, arylene, arylenealkylene, and alkylenearylene are particularly useful as wetting agents in x-ray imaging compositions.
