Abstract

This invention provides a reversible thermochromic composition that exhibits a highly fluorescent red or peach color upon color development, and a reversible thermochromic microcapsule pigment encapsulated therein. The invention comprises at least (a) a fluorane derivative with a specific structure as an electron-donating chromogenic organic compound, (b) an electron-accepting compound, and (c) a reaction medium that reversibly generates the electron transfer reaction by means of components (a) and (b) within a specific temperature range.
