Abstract
A thermal recording material having a heat-sensitive color-forming layer that contains a phosphate modifier in addition to an activator and lueco dye can provide good imaging. The phosphate modifier such as unsubstituted dibenzyl phosphate can be paired with an activator such 3-(4-hydroxyphenyl)propionic acid to provide an environmentally friendly thermal recording material.
