Abstract
The purpose is to provide a laminate useful as a temporary support for producing a large-area, high-definition flexible electronic device, the laminate having stably low adhesive strength between a colorless and highly transparent polyimide film and an inorganic substrate even in the case of a large surface area and having few blister defects. The laminate that attains the purpose is obtained by initially wetting either one of an inorganic substrate coated with the silane coupling agent and a colorless polyimide film with an aqueous medium, and then laminating while pressing out the aqueous medium.
