Abstract

The present invention provides a method for manufacturing a laminate, wherein when a laminate, in which a film and a support base material are stacked upon each other, is manufactured by forming a sacrificial layer on a support body, forming a film such as a CO₂ separation film on the sacrificial layer, bonding the support base material on the film, and then removing the support body and the sacrificial layer, the sacrificial layer can be easily removed with a liquid such as water. The present invention specifically provides a method for manufacturing a laminate, the method including: a step for forming a sacrificial layer on a support body using a sacrificial layer forming composition; a step for forming a film on the sacrificial layer; a step for bonding a support base material on the film; a step for separating the support body after the bonding step; and a step for removing the sacrificial layer by dissolving the sacrificial layer into a liquid after the separation step. In this method for manufacturing a laminate, there is used a sacrificial layer forming composition which includes a resin, a polyol, and a solvent, wherein the resin has a functional group I which is one or more groups selected from the group consisting of a hydroxyl group, a cyano group, and a carboxyl group, and a functional group II which is a hydrophilic group or a hydrophobic group other than the functional group I.
