PROBLEM TO BE SOLVED: To provide a heat-insulating decorative sheet for a floor that prevents warping caused by infrared light.SOLUTION: A decorative sheet 3 is manufactured by forming a thermoplastic resin base layer 11, a printed layer 13, and a surface protection layer 19 in this order. The surface protection layer 19 contains 10 pts.mass or more and 20 pts.mass or less of glass beads 31 having a diameter between 1/3 or more and 2/3 or less of a thickness of the surface protection layer 19, and 3 pts.mass or more and 5 pts.mass or less of a wax component 32. The printed layer 13 includes a solidly printed layer 131 and a pattern layer 132. The solidly printed layer 131 contains a pigment selected from among isoindolinone, disazo, polyazo, diketopyrrolopyrrole, quinacridone, phthalocyanine and titanium oxide, while the pattern layer 132 has a black color reproduced by mixing isoindolinone, diketopyrrolopyrrole, and phthalocyanine pigments.SELECTED DRAWING: Figure 1 |
