PURPOSE:To provide a heat-sensitive recording body with no occurrence of stick during heat-sensitive recording, high luster, high recording density and good contrast. CONSTITUTION:One face of a synthetic paper Upo FPG-80 is coated with a heat-sensitive color development layer coating so as to make the amt. of coating to be 5.5g/m<2>. Then, the above is coated with an intermediate layer coating consisting of a water-soluble resin and/or a water-dispersible resin and a crosslinking agent so as to make the amt. of the coating to be 2.5g/m<2> and the above of the intermediate layer is coated with a luster coating consisting of 375 pts. polysiloxane-grafted acryl emulsion (the solid content: 20%), 40 pts. potassium alkyl phosphate (the solid content: 50%), 7 pts. slurry of 70% calcium carbonate (the mean particle diameter is 2.1mum) and 245 pts. water so as to make the amt. of the coating to be 1.0g/m<2>. In addition, after the opposite face is coated with a back layer coating so as to make the amt. of the coating to be 3.5g/m<2>, supercalender treatment is performed to obtain a heat-sensitive recording body. |
