The domestic two-ply absorbent paper material, with an embossed patterning and in a weight of 10-40 g/m<2>, has a raised point density in each ply of≥10 points/cm<2>, and the surface area of the raised points in each ply is≥5% of the ply surface. At least one ply is embossed with a decorative pattern, with structured projection gaps and angles, which match up with the embossed projections of the other ply. The total surface of the peaks of the projections, bonded together, are at least 15% of the total projection peak surface area of the ply, at the relative positions for the pattern of the two plys. At least 30% or 40% of the embossed projections of one ply form bonds with the embossed projections of the other ply. The total surface of the projection peaks, in a ply, is at least equal to 20% of the projection surfaces of the ply, and is≤30% of the ply surface area and≥7.5% of the ply surface while≤15%. The projection density is preferably≤20 projections/cm<2>. Both plys are embossed with a decorative pattern which can be identical and offset, or different. |
