Description of the Related Art Conventionally, there has been known a display laminated sheet in which a colored resin layer and a hot-melt type adhesive layer are sequentially laminated on a translucent film, and the film can be peeled from the colored resin layer. (Actual fairness 4-30045). In such a laminated sheet, when heat-bonded to a polyester fiber, the disperse dye that dyes the fiber sublimates and migrates to the hot-melt adhesive layer and the colored resin layer, and deposits on the sheet surface to impair the clear display. There is a drawback that In order to prevent the transfer of sublimation, there is a display laminated sheet in which a layer that does not allow the disperse dye to pass through is provided above the interface between the colored resin layer and the light-transmitting film. Not only is the migration resistance insufficient,
The film itself had a bad feeling (softness and feel) and had a problem when used as a laminated sheet for display.

成した。The present inventor can suppress the dye sublimation transfer by providing a barrier resin layer such as an ethylene-vinyl copolymer resin between the colored resin layer and the hot melt adhesive layer. What is possible is that the adhesion between the barrier resin layer and the colored resin layer and between the barrier resin layer and the hot-melt adhesive layer 2 is not good, but the use of a crosslinking agent such as an isocyanate promotes the bonding between the two layers to improve the adhesiveness. The present invention has been completed as a result of intensive studies, focusing on the fact that

By peeling from the resin layer, the display mark can be attached to the article.
Further, the dye used in the article has a high ability to prevent sublimation transfer, and since the dye used in the article does not deposit on the surface of the mark, clear display is possible.

好ましくは２／３〜３／２程度である。The total thickness of the colored resin layer, the barrier resin layer and the hot melt adhesive layer can be selected within a range that does not impair the cutting property, the adhesive strength and the coloring degree, and is usually
The thickness is 80 to 150 μm, preferably about 100 to 120 μm. If the total thickness of the layers is less than 80 μm, increasing the thickness of the barrier resin layer in order to improve the dye sublimation preventive property of the display mark makes the thickness of the hot-melt adhesive layer or the colored resin layer relatively small. It will be easier. When the thickness of the hot-melt adhesive layer is reduced, the adhesive strength is likely to decrease, and when the thickness of the adhesive layer is increased to increase the adhesive strength, the hiding property of the adherend by the colored resin layer tends to be reduced. , A clear display may not be possible. When it exceeds 150 μm, the cutting properties of the colored resin layer, the barrier resin layer and the hot melt adhesive layer are likely to be deteriorated, the colored resin layer is not sharply cut, and burrs are likely to remain on the periphery of the cutting region. The ratio of the thickness of the colored resin layer to the barrier resin layer and the thickness of the hot melt adhesive layer can be selected within a range that does not reduce the coloring degree, hiding degree, dye sublimation preventive property, and adhesive strength. Colored resin layer / barrier resin layer = 20/1 to 1/1, preferably about 14/1 to 11/4, (colored resin layer + barrier resin layer) / hot melt type adhesive layer = 1/4 to / 1,
It is preferably about 2/3 to 3/2.

鮮明に表示する上で有用である。The laminated display sheet of the present invention is useful for marking an article for which a hot-melt adhesive can be heat-bonded, and a barrier resin layer forms a dye layer on the surface of the article to the colorant layer of the dye. Since it prevents sublimation transfer and almost completely prevents the dye from depositing on the surface of the colorant layer, it is useful for clearly displaying the mark.
