Abstract

PROBLEM TO BE SOLVED: To constitute a decorative layer out of a rolled body with a spot-form pattern of a chip aggregate, and impart a high wear-resistance to the decorative pattern extending to the total thickness of the decorative layer by arranging the decorative layer wherein a pattern upper layer having a semi-transparent composition containing a transparent filler and a pattern lower layer are joined and rolled. SOLUTION: By arranging a decorative layer wherein a pattern upper layer having a semi-transparent composition containing a transparent filler and a pattern lower layer are joined and rolled, this decorative material having a drawn pattern of a laminated body comprising the pattern upper layer and the pattern lower layer, is manufactured. In the decorative material 27, a sea section 24 for which the pattern lower layer is rolled, contains more opaque filler substance such as calcium carbonate compared with an island section 26, and contains less transparent filler material such as talk compared with the pattern upper layer. A semi-transparent section 25 for which the pattern upper layer containing the transparent filler material is rolled, expands around the island section 26 by forming cold marks by drawing a thin section. The island section 26 becomes a clear island section of a small unit by cold-drawing a comparatively thick section of the surface upper layer.
