<P>PROBLEM TO BE SOLVED: To restrict generation of bubbles during printing on a heat-sensitive recording layer to prevent deterioration in printed image quality. <P>SOLUTION: In the heat-sensitive recording material obtained by successively laminating the heat-sensitive recording layer on a support, an emulsion of a compound represented by the formula is contained in the heat-sensitive recording layer which excludes the top most heat-sensitive recording layer from the support, and contains a diazonium salt compound and a coupler to develop color reacted with the diazonium salt compound when heated. In the formula, R<SP>1</SP>is a 1-5C alkyl group, aryl group or cycloalkyl group, and R<SP>2</SP>is H, a 1-5C alkyl group, aryl group or cycloalkyl group. <P>COPYRIGHT: (C)2004,JPO |
