    摘要: It is an object of the present invention to provide a heat-shrinkable multilayer film which, in the case of using the heat-shrinkable multilayer film as a heat-shrinkable label for a container, does not produce delamination in covering a container, is superior in heat resistance, oil resistance, tearing properties along the perforation and appearance and can prevent the reduction in strength between the layers after a printing step, and a heat-shrinkable label comprising the heat-shrinkable multilayer film as a base film.The present invention is a heat-shrinkable multilayer film which comprises: an outer surface layer comprising a polyester type resin; and an intermediate layer comprising a polystyrene type resin, said outer surface layer and said intermediate layer being laminated by interposing an adhesive layer comprising a polyester type elastomer or a modified polyester type elastomer.

    摘要: Composite oxide powder has a large specific surface area and a large pore volume even after a high-temperature durability test, without losing oxygen storage ability of a single metal oxide. In this composite oxide powder, a first metal oxide having oxygen storage ability is held as ultrafine particles in the form of islands by a second metal oxide which is different from the first metal oxide, pore volume is not less than 2 cc/g and the first metal oxide particles have a diameter of not more than 30 nm even after subjected to high temperature of 900° C. or more. Since the first metal oxide particles are held in the form of islands by the second metal oxide particles, separated from each other and suppressed from contacting each other, the first metal oxide particles hardly grow granularly.

    摘要: The present invention provides a card base which is degradable by microbes in natural environment. The card base is excellent in properties necessary for card bases, such as tensile strength, impact strength, flex temperature, heat resistance, resistance to thermal expansion and contraction, blocking resistance and humidity resistance, and has rigidity, bending resistance and durability. The card base contains, as essential components, a 3-hydroxybutylate/3-hydroxyvalerate copolymer and a lactic acid polymer, and, where necessary, a polycaprolactone or a high-molecular aliphatic polyester. The card base has a single-layer structure, or a sandwich structure further having overlay layers comprising a composition containing, as essential components, a lactic acid polymer and either or both of a polycaprolactone and a high-molecular alphatic polyester.
