<p>PURPOSE:To fix a display sheet comprised of printing paper firmly within a transparent over-sheet, by a method wherein the over-sheet made of polyethylene terephthalate is joined to the display sheet through an adhesive agent layer containing any of ionomer, an ethylene vinyl acetate copolymer, and a mixture of ionomer and polyethylene. CONSTITUTION:A display sheet 1 is coated with an over-sheet made of polyethylene terephthalate, for example, FUJI PET. A laminator is used for this coating treatment, at the time of this laminate treatment, an adhesive agent is applied to the inside of the over sheet 2 through extrusion coating and an adhesive agent layer 3 of about 50mum in thickness is formed. The adhesive agent containing at least a kind out of ionomer, an ethylene vinyl acetate copolymer, a mixture of ionomer and polyethylene, a mixture of the ethylene vinyl acetate copolymer and the polyethylene, and a mixture of ionomer and ethylene vinyl acetate copolymer is used for the adhesive agent layer 3.</p> |
