PURPOSE: To obtain a heat-shielding sheet being permeable to visible rays, having a high absorptivity of near-infrared rays and being usable for a pressure- sensitive adhesive sheet, a printing sheet, an outdoor marking film or the like by adding a specified compound to a plastic resin. CONSTITUTION: This sheet is made of a mixture comprising a plastic resin and 0.01-5wt.% aluminum compound or a diimonium compound. As the plastic resin, one permeable to visible rays is used. A vinyl chloride resin is particularly desirably used. Examples of the aluminum compounds used include IRA-002 and IRA-003, trademarks of products of Kyodo Chemicals, Ltd. Examples of the diimonium compounds used include IRA-022, etc. The thickness of the heat- shielding sheet is usually 10-1000μm. A pressure-sensitive adhesive layer is laminated on at least either surface of this sheet to form a pressure-sensitive adhesive sheet, and it is combined with an ultraviolet absorber to form an outdoor marking film.
