<P>PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material which can prevent a quality of a printing image from decreasing by suppressing occurrence of bubble at a heat-sensitive recording layer printing time. <P>SOLUTION: This heat-sensitive recording material is constituted by sequentially laminating heat-sensitive recording layers on a support. In this material, the recording layers except the uppermost recording layer from the support, each contains a diazonium salt compound and a coupler reacted with the diazonium salt compound at a heating time, and this recording layer contains an emulsion of a compound represented by formula (1), wherein R<SP>1</SP>is a 1-12C alkoxy group or a 4-12C alkoxy group, and R<SP>2</SP>is a hydrogen atom, a chlorine atom or a methyl group. <P>COPYRIGHT: (C)2004,JPO |
