Abstract: The present invention relates to an adhesive composition, including: 100 parts by weight of an unvulcanized rubber; and from 20 to 100 parts by weight of an adhesive hydrocarbon-based resin with a softening point of 40° C. or less, and also relates to an adhesive foamable sheet including: an adhesive layer including the adhesive composition mentioned above; and a foamable rubber layer including a foaming agent, a curing agent, and an unvulcanized rubber. The present invention can provide an adhesive composition having both good adhesive properties and processability, which can form an adhesive layer in which cold-flow is controlled. In addition, it can provide an adhesive foamable sheet in which cold-flow can be controlled, having an adhesive layer consisting of the adhesive composition mentioned above.

Abstract: The present invention relates to a hexahedron-type layered product having a top surface, a bottom surface and four side surfaces, which contains: a first layer; and a second layer which has a deformability higher than that of the first layer, wherein at least one of the side surfaces is formed by only the first layer. In accordance with the present invention, even if the layered products, each being formed by a layer which has a smaller deformability and another layer which has a larger deformability, are stored for a long period of time, for example, in a stacked manner, the protrusion of the layer which has a larger deformability from the side surfaces of the layered product can be controlled or prevented, and the integration of the layered products themselves or adhesion of the layered products to a package container can be reduced or prevented.
