Zusammenfassung:To provide a manufacturing method of a laminate having a film with a print layer with a reduced surface level difference due to the print layer.SOLUTION: A manufacturing method of a laminate 100A includes: a step (i) of forming a print layer 12 containing a color ink layer 13 and a transparent ink layer 14 on a base material film 11 to obtain a first film 1; and a step (ii) of disposing a second film 2 on the print layer 12 of the first film 1, interposing an adhesive layer S1. The step (i) includes a step (a) of printing a color ink on the base material film 11 to form a color ink layer 13; and a step (b) of printing a transparent ink on the base material film 11 to form the transparent ink layer 14. The step (b) includes a step (b1) of printing the transparent ink on a region where no color ink layer 13 is formed on the base material film 11.SELECTED DRAWING: Figure 4 【課題】印刷層に起因する表面段差が低減された印刷層付きフィルムを有する積層体の製造方法を提供すること。【解決手段】基材フィルム11上に色インキ層13と透明インキ層14とを含む印刷層12を形成して第一のフィルム1を得る工程(i)と、第一のフィルム1の印刷層12上に接着剤層S1を介して第二のフィルム2を配置する工程(ii)と、を備え、工程(i)が、色インキを基材フィルム11上に印刷して色インキ層13を形成する工程(a)と、透明インキを基材フィルム11上に印刷して透明インキ層14を形成する工程(b)と、を含み、工程(b)が、基材フィルム11上の色インキ層13が形成されない領域に透明インキを印刷する工程(b1)を含む、積層体100Aの製造方法。【選択図】図4
