<p>Provided are a porous layer layered body improved very much in film strength, heat resistance, chemical resistances, and others as well as in the adhesion between its substrate and its porous layer by the formation of a crosslinked structure; a production process thereof; a functional laminate using the porous layer layered body; and a production process thereof. The layered body is a layered body including a base, and a porous layer on at least one surface of the base; and further the base is a resin film made of at least one resin material selected from the group consisting of polyimide resins, polyamideimide resins, polyamide resins, and polyetherimide resins, or is a metal foil piece, and the porous layer is made of a composition containing at least one polymer selected from the group consisting of polyimide resins, polyamideimide resins, polyamide resins, and polyetherimide resins as a main component, and a crosslinking agent. Additionally, the porous layer has fine pores having an average pore diameter of 0.01 to 10 µm, and a porosity of 30 to 85%.</p> |
