PURPOSE:To provide the title recording material capable of multi-gradation multicolor expression with high sensitivity, which comprises a transfer sheet having a transfer layer comprising a sublimable coupler and a high softening point binder as main constituents and a receiving sheet having a receiving layer comprising a specified diazonium salt and an organic basic compound as main constituents. CONSTITUTION:The objective recording material is obtained by using (A) the transfer sheet comprising a transfer layer on a base and (B) the receiving sheet comprising a receiving layer. The transfer layer comprises (i) a sublimable coupler, preferably, a low molecular weight one having a subliming temperature of 70-200 deg.C, e.g., resorcinol, and (ii) a high softening point binder, preferably, one having a softening point of not lower than 100 deg.C, e.g., ethyl cellulose, as main constituents. The receiving layer comprises as main constituents (i) a diazonium salt capable of reacting with the coupler to form a coloring matter, e.g., 2-5-diethoxy-4-dimethylaminobenzendiazonium chloride, and (ii) an organic basic compound, preferably, a compound of the formula or the like in the state of a particulate dispersoid with a particle diameter of 0.1-10mum. |
