Battery packaging material wherein a sheet-like laminated body is formed by sequentially stacking at least a base layer, metal layer, and sealant layer, the battery packaging material being equipped with substantially rectangular space that is formed to protrude from the sealant layer side toward the base layer side, and accommodates a battery element on the sealant layer side. In planar view from the base layer side view, a first and second curved sections are provided from the center portion toward the battery packaging material end parts, in a cross section in the thickness direction on a line connecting opposing corner parts protruding in a substantially rectangular shape. The thickness (a) of the metal layer at the first curved section, (c) of the metal layer at the second curved section, and (b) of the metal layer at the section located between the first and second curved sections, satisfy the following relationship a≧b>c or a≧c>b.

A battery packaging material has an excellent ink printing characteristic on a base-layer-side surface. This battery packaging material has a laminated body formed by sequentially stacking at least a base layer, a metal layer, and a sealant layer, with the wet tensile strength of the surface of the base layer being 32 mN/m or greater.

A method of producing a laminated article comprising placing a first metal skin, a core, and a second metal skin freely onto each other as discreet layers to provide a layered component; and forming the layered component into a shaped article via a die prior to producing a laminated article by applying pressure and heat to the shaped article, wherein at least the first skin moves relative to the core and/or second skin during the forming.

The invention relates to an edge material for panels, the edge material being constructed from a plurality of bonded layers. The edge material comprises a first layer, which is non-metallic, and a core layer, which is made of at least one metal layer. The edge material also comprises a second layer, which is non-metallic. Furthermore, the invention relates to a corresponding sandwich panel and to a corresponding cover layer for panels.

There are provided an interlayer for laminated glass having a multilayer structure, capable of sufficiently suppressing generation of air bubbles and increase of area of air bubbles when the interlayer is made into a laminated glass. The interlayer for laminated glass includes alternately laminated at least one skin layer and two or more core layers, the skin layer having a storage modulus of 1.0×10.sup.6 Pa or more measured by a dynamic viscoelasticity test under conditions of a frequency of 1 Hz, a swing angle gamma of 0.01% and a temperature of 20° C., and the core layers having a storage modulus of less than 1.0×10.sup.6 Pa, wherein a value of a product of a value obtained by averaging thicknesses (mm) of the respective core layers and a thickness (mm) of the whole interlayer for laminated glass is 0.15 or more.

An aviation laminate includes an intumescent backer sheet covered by a decorative sheet. The aviation laminate is generally fire-resistant, may be structural, and may be used to construct various components within an aircraft cabin that may be held to government/regulatory fire mitigation requirements.

The object is to provide a resin composition for a printed circuit board capable of realizing a printed circuit board that not only has heat resistance and flame retardancy but also is excellent in heat resistance after moisture absorption. The resin composition is a resin composition for a printed circuit board containing a cyanate ester compound (A) obtained by cyanation of a naphthol-dihydroxynaphthalene aralkyl resin or a dihydroxynaphthalene aralkyl resin, and an epoxy resin (B).
