。(Conventional technology) In order to impart scratch resistance and abrasion resistance to a substrate made of hard vinyl chloride resin, a synthetic resin solution such as cross-linked epoxy resin is applied to the substrate surface, and this coated surface is tertiary coated. Original crosslinking treatment (hard coat treatment) is performed.

難であった。(Problems to be Solved by the Invention) However, since the hard coat treatment using the above-mentioned cross-linked epoxy resin is usually applied directly to the substrate by dipping, roll coater, spraying, etc., the coated surface is smooth. It was difficult to form a clear printed surface on the coated surface.
また、基材上に印刷を施した後、上記ハードコート処理

徴とする積層板の製造方法にある。(Means for Solving the Problems) The present invention has discovered a method for manufacturing a laminate that can solve the above-mentioned problems, and its gist is that: a substrate made of a hard vinyl chloride resin ( 1) On top of that, a printing film (2), a transparent adhesive layer (3), and a crosslinked resin (5
) The hard coat treated film (4) made of a polyester resin film or a polycarbonate resin film coated with a polyester resin film (4) is arranged in order so that the hard coat treated part is on the outside, and then heat pressed to heat-fuse each layer. There is a method for manufacturing a laminate.
以下、本発明を添付図面によって説明する。The present invention will be explained below with reference to the accompanying drawings.
第１図は本発明に係る積層板の熱プレス前の状態を示寸
断面概略図である。FIG. 1 is a schematic cross-sectional view showing the state of the laminate according to the present invention before hot pressing.

。In FIG. 1, reference numeral 1 denotes a substrate made of hard vinyl chloride resin, and as shown in the figure, a plurality of sheets 1- stacked one on top of the other can also be used. A printing film 2 on which desired characters, designs, etc. have been applied in advance is placed on the substrate 1. As the printing film, a vinyl chloride resin film is preferable because it has good heat fusion properties with the substrate. As the printing method, normal printing methods such as gravure printing and offset printing are applied.
さらに、上記印刷フィルム２の」−に透明接着剤層３を

トメルト系熱架橋型の接着剤が好ましい。Furthermore, a hard-coated film 4 is placed on top of the printing film 2 with a transparent adhesive layer 3 interposed therebetween. Although various transparent adhesives can be used for the transparent adhesive layer 3, hot-melt thermally crosslinkable adhesives are preferred from the viewpoint of strength during thermal fusion.
ハードコート処理フィルム４には耐熱性の高いポリエス

平坦な外表面が得られる。As the hard coat treated film 4, a polyester resin film or a polycarbonate resin film with high heat resistance is used. In other words, if a polyester resin film or a polycarbonate resin film whose softening temperature is higher than that of hard vinyl chloride resin is used, the hard coat treated film will not elongate or deform during heat pressing, and as a result, the crosslinked resin will not experience craze, etc. A flat outer surface is obtained without any intrusion.

機等を使用し、熱プレスして各層間を熱融着する。One side of the film is coated with a crosslinked resin to form a Bartco-1-treated side. As the crosslinked resin, a type of prepolymer such as an epoxy resin or a silicone resin that is crosslinked and cured after application can be suitably used. The hard coat treated film 4 is placed with the treated side facing outward. Next, after disposing the above-mentioned layers in order, the layers are heat-sealed by heat pressing using a heat press machine or the like.
熱プレスする際のプレス条件は通常の硬質塩化ビニル樹
脂板で実施される条件が好ましい。The pressing conditions for hot pressing are preferably those used for ordinary hard vinyl chloride resin plates.
具体的にはプレス温度が１７０〜１８０℃程度、プレス
圧が２０〜１００Ｋｇ／Ｃ１１２程度の条件で各層間の
熱融着に優れたものが得られる。Specifically, a product with excellent heat fusion between layers can be obtained under conditions of a press temperature of about 170 to 180° C. and a press pressure of about 20 to 100 kg/C112.
