PURPOSE:To prepare a titled recording material in which a plural number of recording sheets is adhered by pressure so that they can be peeled, a surface color development layer is formed on an uppermost sheet, an intermediate color development layer, containing a thermofusing material, is formed between the sheets, and a plural number of sheets can be simultaneously recorded by one- time recording. CONSTITUTION:A surface color development layer, consisting of a coating layer 11 containing a diazo compound and a coupler, is formed on a surface of a sheetform support product 10, and a coating layer 12, containing a diazo compound and a thermofusing material, such as paraffine wax with a melting point of about 50-120 deg.C, is formed on the back to form an uppermost recording sheet T. Meanwhile, a coating layer 21, containing a coupler, is formed on a surface of a sheetform support product 20 to form a lowermost recording sheet B. The sheets A and B are laminated, and an intermediate color development layer, consisting of the coating layers 12 and 21, is formed between the sheets to form a plural number of sheets of diazo system heat-sensitive recording material. |
