ABSTRACT OF THE DISCLOSURE A process for producing decorative articles having patterns of surface concavities and convexities (unevennesses) comprises the steps of : 1) placing into mutual contact and laminating a hardenable decorative material layer and an expan- sion-contraction deformable sheet provided with regions susceptible to expansion-contraction de- formation and regions not susceptible to said de- formation; 2) causing the deformable sheet to undergo said de- formation under pressure thereby to impart a pattern of unevennesses to the decorative material layer in contact with the sheet; and 3) causing the hardenable decorative material layer to fully harden. The sheet deformed under pressure imparts a unique pattern of surface unevennesses corresponding to the two kinds of regions to the decorative material layer. Decorative articles thus obtained can be ap- plied to a wide variety of uses as materials for decorating architectural exteriors and interiors and as decorative boards. The degree of surface unevenness can be controlled by adjusting the pressure. Colored patterns corresponding to the unevennesses can also be formed.
