Paragraph 0136-0142, (2013/07/31)
Provided is a novel developer capable of realizing a thermal recording material which shows extremely high color-developing sensitivity, affords good image density even when printed at a low application energy (i.e., high start-up sensitivity), and is superior in heat resistance and plasticizer resistance, and a thermal recording material using the developer. Phenolsulfonic acid aryl ester represented by the following formula (1) wherein each symbol is as defined in the description.
