PURPOSE:To prepare a diazo system heat-sensitive record peeling paper which is excellent in heat-response efficiency and a long-term preservation ability and is fixable, by a method wherein a diazo system heat-sensitive color development layer is formed on one side of a support product and a peeling paper is provided on the other side. CONSTITUTION:A heat-sensitive color development layer 2 consisting of a diazo compound, such as compounds shown in a formula, and a coupler, such as phenol, which is a compound reacting with said diazo compound and color- develops it, is formed on one side of a support product 1, and a peeling paper 4 is formed on the other side through a pressure-reducing adhesive layer 3, if necessary, to prepare a titled haat-sensitive record peeling paper. |
