ABSTRACT OF THE DISCLOSURE By the use of improved decorative sheets each comprising (a) a hydrophilic deformative sheet which is susceptible to expansion deformation by swelling caused by water absorption and (b) a moisture penet-ration controlling layer formed on the entire surface of at least one side of the hydrophilic deformative sheet, each decorative sheet being designed to differ, depending upon regions of the sheet, in the degree of expansion deformation caused by water absorption, decorative articles each having a deep and clear sur-face unevenness or relief pattern can be obtained on hardened water-containing plastic materials. These decorative articles are applicable to various uses such as architectural materials (interior and exterior materials for walls, ceilings, etc.), decoration boards and panels, materials for sign boards and materials for packaging. |
