<p>PROBLEM TO BE SOLVED: To provide a decorative sheet showing an upgraded environmental safety and an improved interlayer adhesion. SOLUTION: This decorative sheet comprises at least a base material sheet 2, an ink layer 11 consisting of a solid ink layer 3 and/or a pictorial pattern ink layer 4, an adhesive layer 5 and a transparent resin layer 6, these layers being sequentially laminated. In addition, at least, one layer or more selected from among the solid ink layer 3, pictorial pattern ink layer 4 and adhesive layer 5, are formed of an aqueous coating agent. This aqueous coating agent contains an aqueous urethane resin, so that the described issue is solved. In this case, the transparent resin layer is preferably formed by a melt-extrusion coating process and the content of the aqueous urethane resin is preferably equivalent to 25 wt.% or more of a binder component in the layer formed of a water coating agent. In addition, in terms of concrete state, the base material sheet 2 is preferably a colored sheet composed of a polyolefin elastomer and the transparent resin layer 6 is a polyolefin resin layer.</p> |
