A laminate of ion exchange membranes suitable for water purification comprises a plurality of anion exchange membranes (AEMs) and a plurality of cation exchange membranes (CEMs), in which color characteristics of the AEMs are visually different from color characteristics of the CEMs. The present invention also provides a method of manufacturing a film laminate in which the likelihood that there are two consecutive films having the same charge is reduced. In addition, it is easy to identify whether or not two continuous films having the same charge are present in the laminate. 一种适合于水纯化的离子交换膜的层叠体，其包含多个阴离子交换膜(AEM)和多个阳离子交换膜(CEM)，其中AEM的颜色特性与CEM的颜色特性可见地不同。本发明还提供了制造膜层叠体的方法，其中降低了存在两个连续膜具有相同电荷的可能性。此外，容易识别出在层叠体中是否存在具有相同电荷的两个连续膜。
