Patent ID: 8252138

Claim:
A method for producing a thermosensitive multiple recording sheet by laying at least two thermosensitive recording sheets one upon another comprising: attaching a paper or film second base material having a basis weight of 5 to 40 g/m 2 and a density of 0.85 to 1.3 g/cm 3 in case of a paper second base material or a density of 0.9 to 1.6 g/cm 3 in case of a film second base material onto a side of a recording layer of a first thermosensitive recording sheet which comprises a first base material, through a temporary adhesive layer to obtain a laminated sheet comprising the first thermosensitive recording sheet, the temporary adhesive layer and the second base material; and forming a thermosensitive recording layer on the surface of the second base material in the laminated sheet to form a second thermosensitive recording sheet laminated on the first thermosensitive recording sheet, wherein said attaching comprises: coating a coating liquid containing a temporary adhesive in a dissolved or a emulsified state in a vehicle onto the first thermosensitive recording sheet or the second base material at a coating weight of 1-5 g/m 2 while the coated layer is in a wet state; laminating the first thermosensitive recording sheet and the second base material through the coating liquid; and drying the coating liquid under a pressure of about 1 kg/cm or less after laminating the second base material.
