    Abstract: PURPOSE:To obtain a functional sheet, having a low water absorptivity and expansion coefficient in dipping thereof in water in spite of a required moisture permeability possessed thereby, bondable with a water-based adhesive, good in draining of water in the adhesive, excellent in optical characteristics and further good in various properties such as heat, scratch and gas permeation resistance and mechanical characteristics. CONSTITUTION:This functional sheet is composed of a film-formed sheet made of (A) a polymer alloy prepared by graft modifying a water-soluble vinyl alcoholic polymer with an ethylenically unsaturated monomer or a composition of the polymer alloy (A) with (B) an aqueous cross-linking agent or its heat- treated or aged product. The gas permeability of the functional sheet is >=50g/m .24hr,
