Abstract

To provide a manufacturing method of a laminate which is excellent in economic efficiency and environmental load reduction and which has no poor appearance such as orange peel skin.SOLUTION: A manufacturing method of a laminate having at least a substrate 1, a printing layer formed of a plain part and a printing part, an adhesive layer formed from a reactive adhesive containing a polyol main agent and a polyisocyanate curative agent, and a substrate 2, in this order, comprises: a step 1 of applying the reactive adhesive to the printing layer of a printed matter having the printing layer formed of at least the substrate 1, the plain part, and the printing part so as to satisfy 0.5 (g / m2: solid content conversion)<CW1<CW2 when the application amount of the reactive adhesive on the plain part is CW1 (g / m2: solid content conversion), and the application amount of the reactive adhesive on the printing part is CW2 (g / m2: solid content conversion); and a step 2 of laminating the substrate 2 on the surface applied with the reactive adhesive.SELECTED DRAWING: None
