A sand-effect paper material comprises a substrate, formed by a mixture of cellulose fibres and containing at least one polymeric substance (comprising, for example, one or more colophony-based and/or alkyl-ketene-dimer-based and/or epichlorohydrin-based resins, and/or modified starches, etc.), apt to bestow strength on the mixture of fibres, and an inorganic filler (for example, a mineral filler of a carbonate type, kaolin, talc, etc.); the paper material has at least one surface treated with at least one surface adhesive and provided with a glossy coating formed by one or more binding polymers and/or waxes, mixed with pigments, so that the paper material has a sand-like feel. |
