A recording material comprising a color-revealing composition, and a color-revealing composition.

摘要

embossing material containing a color developing composition, and color developing composition is revealed to be a recording material having excellent heat resistance, which contains only a small amount of a dihydroxydiphenylsulfone derivative. Also disclosed is a color developing composition which is used to form the recording material. The color development composition provides a recording material having excellent heat resistance in the bottom portion. the color developing composition may have the reduced dihydroxydiphenylsulfone derivative content, such as 4,4'-dihydroxydiphenylsulfone at 2 wt% or less, or additionally at 1 wt% or less.
