Schematic view for thermochromic response of fluoran-gallate system: a Thermochromic effect of fluoran to heat and cooling. b Leuco dye (fluoran, white circle), developer (gallate) and solvent (R-OH) before commencement of heat where interaction of fluoran and gallate occurs at ambient temperature showing development and stabilization of color development; c Heat causes lactonization of the fluoran and eliminating interaction with developer and solvent
