| titleOfInvention | Thermal recording material |
| abstract | PURPOSE:To obtain a thermal recording material excellent in heat responsivity, color developing speed and developed color density and also in preservability of images, by using at least one specified fluoran derivative as a thermal color forming component in a thermal recording material. CONSTITUTION:At least one fluoran derivative of formula I , which is obtained, e.g., by bringing 4-N,N-di-subst.amino-2-hydroxy-2'-carboxybenzophenone of formula II, wherein R1 is a lower alkyl group and R<2> is a lower alkyl group, an aryl group or the like, and 4-methoxy-6-methyl-benzylaniline derivative of formula III, wherein R3 is an electron-attractive group such as halogen, an acyl group or a carboxyl group and R4 is hydrogen or formula IV (wherein R5 is an electron-attractive group) into reaction in the presence of sulfuric acid or the like, is applied to a base together with an ordinary color developer and auxiliary components such as a binder, a filler or a heat-fusible substance to produce a thermal recording material. |
