具有聚酰亚胺层的层叠体的制造方法、聚酰亚胺膜的制造方法
摘要：
本发明提供一种连续地制造具有卷曲减少的具有聚酰亚胺层的层叠体的制造方法、聚酰亚胺膜的制造方法。一种具有聚酰亚胺层的层叠体的制造方法，其是在支撑基材上具有一层以上的聚酰亚胺层的层叠体的制造方法，其中：包括使用长条状的可挠性膜作为支撑基材，将聚酰胺酸溶液或聚酰亚胺溶液涂布在支撑基材上而形成一层以上的涂布层的涂布步骤；一面搬送具有涂布层的支撑基材一面进行加热处理的加热处理步骤；在加热处理步骤中，通过握持支撑基材的宽度方向的端部的机构，一面将具有涂布层的支撑基材的宽度方向的端部固定或在宽度方向上拉伸，一面在传送方向上搬送支撑基材，而形成聚酰亚胺层。
摘要（英）：

The invention provides a method for manufacturing a curl reduced multilayer body having polyimide layers and a method for manufacturing polyimide film. The method for manufacturing the multilayer body having the polyimide layer comprises the steps: the multilayer body comprises more than one layer of polyimide layer on a support substrate, wherein a flexible film serves as the support substrate, the support substrate is coated by a polyamide acid solution or a polyimide solution, so that more than one coating layers are formed; the support substrate having coating layers is moved while one side of the support substrate is heated; in the last step, a mechanism on the end in the width direction of the support substrate is holden, the end in the width direction of the support substrate having the coating layer is fixed or stretched in the width direction, the support substrate is moved in the convey direction, then polyimide layers are formed.
