摘要： The present invention relates to a multilayered film having a high degree of freedom regarding selection of a material and a decoration method, which is not only excellent in handling properties and low-temperature adhesiveness to adherends of various materials but also applicable to decorative molding of every sort in a three-dimensional solid shape, and a method for producing the same. The present invention provides a multilayered film including, as an intermediate layer (X), a thermoplastic resin layer having a bending rigidity of 60 to 30,000 kPa·mm 3 ; a layer (Y) composed of a thermoplastic polymer composition on both surfaces of the intermediate layer (X), the thermoplastic polymer composition containing 0 to 50 parts by mass of a polypropylene-based resin (B) based on 100 parts by mass of a thermoplastic elastomer (A) that is a block copolymer containing a polymer block (a1) composed of an aromatic vinyl compound unit and a polymer block (a2) composed of a conjugated diene compound unit; and a decorative layer (Z) closely arranged on the surface of either one of the layers (Y). The present invention also provides a method for producing the multilayered film, including bringing the thermoplastic resin layer (Y) as a surface layer in a molten state into contact with a roll whose surface is made of a hydrophobic resin.

摘要： Paste which is prepared by any solid concentration and is excellent in terms of handleability, applicability, and storage stability; an electrolyte film or electrode film which is an even and highly flexible coating film formed in a desired thickness from the paste through a few repetitions of an application/drying step; and a polymer transducer which can be industrially and economically produced and shows excellent performance. The paste comprises: a solid polyelectrolyte (A) consisting of a block copolymer containing; a polymer block (a-1) which is represented by chemical formula (1)

and a polymer block (a-2) which has substantially no ionic group and is rubbery at room temperature; an organic solvent (B) having a boiling point at 150°C or higher; and non-dissociable particles (C) which are insoluble in the organic solvent (B) and have a major-axis length of 1 - 100µm and an aspect ratio of 5 or less. The polymer transducer comprises an electrolyte film and a pair of electrode films between which the electrolyte film is sandwiched, wherein the electrolyte film or the pair of electrode films has been formed by drying and solidifying the paste into a film shape.
