지지체 및 그 위에 박리 가능하게 배치된 투광성 수지층을 갖는 적층체의 제조 방법으로서, 지지체 상에, 투광성 수지층을 형성하기 위한 수지 용액을, 도포 두께 a (㎛) 와 지지체의 두께 b (㎛) 의 비 a/b 가 0.5 ∼ 5.8 이 되도록 도포하는 공정, 수지 용액의 도막을 가열하여 건조시키는 공정, 가열시의 온도보다 낮은 온도로 유지하여, 도막을 갖는 지지체의 폭 방향 단부의 컬량을 5 ∼ 50 ㎜ 로 조정하는 공정, 및 컬량이 조정된 도막을 갖는 지지체를 가열 처리하는 공정을 포함한다. Provided is a method for manufacturing a laminate having a support body and a translucent resin layer releasably arranged on the support body, the method comprising: a step for applying a resin solution for forming the translucent resin layer onto the support body so that the ratio a/b of an application thickness a (μm) to a thickness b (μm) of the support body becomes 0.5 to 5.8; a step for heating and drying a film of the resin solution; a step for adjusting the amount of curl at a widthwise end of the support body having the film to 5 to 50 mm while keeping a temperature lower than a temperature during heating; and a step for performing heating processing of the support body having the film of which the amount of curl has been adjusted.
