Abstract
Abstract A decorative laminated structure having on its surface a pattern composed of concaves and convexes which are formed by local heat shrinkages of a layer of a heat-shrinkable resin sheet employed. Such decorative laminated structure can be obtained by laying a base, a heat-shrinkable resin sheet and a picture layer containing at least a plurality of heat sensitive picture areas in a predetermined order to form a composite material, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet; and irradiating the resulting composite material with a heat ray to cause said heat-shrinkable resin sheet at its portions corresponding to said heat sensitive picture areas to cave in, thus forming concaves. The present decorative laminated structure has, alone or in combination with the other structures, a wide variety of uses, for example, not only as a material for a ceiling, a floor, a wall and/or an interior decoration of a building, car, ship and the like but also as a decorative material for furnitures, fittings, tables, musical instruments, cabinets and the like.
