PROBLEM TO BE SOLVED: To provide a printed structure being capable of acquiring authorization for fire protection as an incombustible material while satisfying characteristics required for a printed structure.SOLUTION: A printed structure is a laminate including a pressure sensitive adhesive layer, a printed layer, and a substrate film laminated in this order, in which the printed layer is printed by using a solvent-based ink, the substrate film is composed of a vinyl chloride resin composition containing a vinyl chloride-based resin with an average degree of polymerization of 600 to 1,300 and a plasticizer, and the content of the plasticizer is 15 to 40 pts.wt. based on 100 pts.wt. of the vinyl chloride-based resin, the pressure sensitive adhesive layer is composed of a pressure sensitive adhesive composition containing an acrylic pressure sensitive adhesive with a weight average molecular weight of 600,000 to 1,000,000, and the laminate has thickness of 65 to 160 μm, and has a total calorific value of an exothermic test with a Cone calorimeter testing machine using a gypsum plaster board with thickness of 12.5 mm as a base material of 8 MJ/mmor less. |
