Beschreibung
Zusammenfassung:The present invention provides a multilayer body of an inorganic substrate and a highly heat-resistant transparent film which has sufficient heat resistance and is able to be mechanically separated from the inorganic substrate after being subjected to various processes on the inorganic substrate since the adhesion between the highly heat-resistant transparent film and the inorganic substance is adequately weak. A multilayer body of a highly heat-resistant transparent film and an inorganic substrate, wherein: an adhesive is not substantially used; the peel strength between the highly heat-resistant transparent film and the inorganic substrate is 0.3 N/cm or less; and the CTE of the highly heat-resistant transparent film is 50 ppm/K or less.
