摘要：<p>Provided is a recording material with a superior heat resistance and having a low content of a dihydroxydiphenylsulfone derivative, and a color-developing composition for producing the recording material. With the use of this color-developing composition, a recording material with a superior heat resistance at the background part can be provided and the content of a dihydroxydiphenylsulfone derivative, such as 4,4'-dihydroxydiphenylsulfone, in the color-developing composition can be reduced to 2% by mass or less, or further to 1% by mass or less.</p>
