Abstract

A laminate is formed by laminating a substrate and a support plate through an adhesive layer and a release layer. The release layer is formed by applying a composition containing a reactive polysilsesquioxane and a crosslinkable group-containing siloxane onto the surface of the support plate or the surface of the substrate and heating the composition to polymerize the reactive polysilsesquioxane and the crosslinkable group-containing siloxane.
