ABSTRACT:
Heat-sensitive composition containing (1) at least two reactants which at normal room temperature do not react with each other, but which, upon application of thermal energy, undergo a chemical change which results in change of color, and (2) a non-complexing phenolic compound which enhances the color forming reaction. This composition can be applied to a substrate, such as, for example, paper of film, in order to form a heat-sensitive imaging sheet.
