PURPOSE:To provide a heat sensitive material excellent in color formability at the time of high speed recording, preservability and the stability of a color image, obtained by forming a heat sensitive color forming layer containing a color formable colorless dye, P-hydroxybenzoic esters and a specific compound. CONSTITUTION:A colorless or light colored color formable dye (A), 100-700 pts.wt. (per 100pts.wt. component A) P-hydroxybenzoic esters shown by formula I (wherein R is 1-4C alkyl, benzyl or phenyl) (B) and 10-200pts.wt. (per 100 pts.wt. component B) compound shown by formula II (wherein R1-R3 are H or 1-4C alkyl but simultaneously take no H) [e.g., bis(3-butyl-4-hydroxy-6- methylphenyl)sulfide] are respectively dispersed in a binder to form a dispersion which is, in turn, mixed to obtain a coating liquid. This coating liquid is applied to a support and dried to obtain an objective recording material. |
