A sheet of paper, in particular for a sanitary paper, consists of at least one ply of absorbent, creped paper of a specific surface weight between 12-35 g/m.sup.2 evincing first and second protrusions respectively (10, 2) respectively arrayed in a first and second pattern. The first pattern is composed of pattern elements each constituted by at least one of the first protrusions (10) and is comparatively well spaced apart mutually, while the second so-called background pattern comprises the second protrusions (2) arranged in more compact manner between the pattern elements. The sheet of paper is characterized in that the pattern elements form a graphic pattern while being arrayed at a rate of at most 0.5 element/cm.sup.2 and the first protrusions (10) constituting them evince at their top a line-shaped surface with a width between 0.1-2 mm, the second protrusions (2) being arrayed at the rate of at least 30, and preferably 40, protrusions/cm.sup.2 and ensuring the essential functional features.
A sheet of paper comprising at least one ply of creped absorbent embossed paper having a surface weight of between 12 and 35 g/m.sup.2 and including first embossed protrusions and second embossed protrusions arranged respectively in a first pattern and in a second pattern and having corresponding cavities on a side opposite to that side having said first protrusions and said second protrusions, the first pattern comprising spaced pattern elements each made up of at least one of said first protrusions, and the second pattern comprising said second protrusions arranged between said pattern elements of the first pattern, wherein the pattern elements of the first pattern form a graphic pattern by being distributed at most at a rate of 0.5 element/cm.sup.2, the first protrusions constituting the pattern elements have at their top a line-shaped surface with a width between 0.1 and 2 mm, and the second protrusions are arranged at a rate of at least 30 protrusions/cm.sup.2.
Stratified sheet of paper comprising at least two creped absorbent embossed paper plies having a surface weight of between 12 and 25 g/m.sup.2 and placed one on the other, each having on one side first embossed protrusions and second embossed protrusions and having corresponding cavities on an opposite side, said one side of each ply pointing inward the stratified sheet, said first protrusions and said second protrusions being arranged respectively in a first pattern and a second pattern, the first pattern comprising pattern elements each constituted by at least one of said first protrusions and being spaced apart from one another, and the second pattern comprising said second protrusions arranged between said pattern elements of the first pattern, wherein the pattern elements of the first pattern form a graphic pattern and are distributed on the sheet's surface at a rate of no more than 0.5 element/cm.sup.2, the first protrusions constituting said pattern elements have at their top a line-shaped surface of a width between 0.1 and 2 mm and the second protrusions are arrayed at a rate of at least 30 protrusions/cm.sup.2.
