In a heat-sensitive recording material which comprises a substrate and a heat-sensitive recording layer thereon containing a diazonium salt and coupler compound, the heat-sensitive recording material characterized in that the coupler compound comprises at least one compound represented by the formula [I] below <IMAGE> [I] wherein R1, R2, R3, R4, R5, R6, R7 and R8 are each hydrogen atom, halogen atom, alkyl or alkoxyl; R9 is hydrogen atom or alkyl; X and Y are each hydrogen atom, -OR10 or -N(R11)(R12), R10, R11 and R12 being each hydrogen atom, alkyl, alicyclic group, aryl or aralkyl, these R10, R11 and R12 may have a substituent selected from among halogen atom, alkyl and alkoxy, R11 and R12 may link together to form a heteroring, or, one or both of R11 and R12 may form a heteroring together with an adjacent benzene ring; n is 0 or 1.
