Abstract:
The invention provides a phenolsulfonic acid aryl ester represented by formula (1) wherein each symbol is as defined in the description. The phenolsulfonic acid aryl ester is useful as a developer to provide a thermal recording material with good color-developing sensitivity, image density when printed at a low application energy (i.e., high start-up sensitivity), and heat and plasticizer resistance. The invention also provides a thermal recording material using the developer.
