    Abstract: The thermosetable composition incorporating organo-iodine compounds that provide improved x-ray contrast are prepared by reacting an epoxy resin with crosslinking agents, wherein the crosslinking agents include compounds having iodo-phenyl functionalities, and wherein the iodine atoms include iodine-127 isotope. The resulting thermoset material includes sufficient iodine-127 isotope covalently bound to the polymer matrix to impart excellent x-ray contrast. The cured polymer materials of this invention may be utilized as underfill material for electrical components, thereby facilitating use of x-ray analysis to detect problematic voids in the underfill.
