Claims8
A spectacle frame comprising:
- a front piece;
- a pair of side pieces joined to the ends of the front piece;
- wherein said front piece and/or said side pieces are formed by multi-layered elements comprising at least one layer of polymeric material and at least one layer of metallic material joined together by means of a layer of adhesive material;
- wherein said layer of metallic material is arranged on outer surfaces of said front piece and/or of said side pieces;
- wherein said polymeric material is cellulose acetate;
- and
- wherein the layer of adhesive material is placed between a joining surface of the layer of polymeric material and a joining surface of the layer of metallic material, said joining surfaces having superficial roughness values different from each other;
- and
- wherein the layer of metallic material has a smaller thickness than the layer of polymeric material.
