         3 . The cleaning article of  claim 1  wherein the coating ( 112 ) has a basis weight of 5-50 g/m 2 . 
     
     
         4 . The cleaning article as claimed of  claim 1  wherein the base material has a basis weight of not more than 150 g/m 2  and at least 30 g/m 2 . 
     
     
         5 . The cleaning article of  claim 1  wherein when an imaginary grid ( 200 ) of parallel, equidistant lines running at right angles to one another and having an edge length of 20 mm of each grid square ( 206 ) is placed over the first side face ( 102 ) of the cleaning article ( 100 ), the first side face ( 102 ) does not have any grid square free of coating. 
     
     
         6 . The cleaning article of  claim 1  wherein the distance of any coating line ( 114 ) from at least one adjacent coating line ( 114 ) in any desired direction is not more than 20 mm. 
     
     
         7 . The cleaning article of  claim 1  further comprising wherein there are at least 5 interfaces ( 208 ) of any coating lines ( 114 ) over an area of 25 cm 2 . 
     
     
         8 . The cleaning article of  claim 5  wherein there is at least one interface ( 208 ) and at most 30 interfaces ( 208 ), in at least 50% of the grid squares ( 206 ). 
     
     
         9 . The cleaning article of  claim 1  wherein there is a coherent structure of coating lines ( 114 ) across the coating ( 112 ) from one lateral edge ( 122   a ) of the cleaning article to the opposite lateral edge ( 122   b ) at least in sections. 
     
     
         10 . The cleaning article of  claim 9  wherein the coating lines ( 114 ) are arranged in such a way that there are no interruptions between the coating lines ( 114 ) at least in sections in a cross direction ( 212 ) of the cleaning article. 
     
     
         11 . The cleaning article ( 100 ) of  claim 1  wherein the coating ( 112 ) has or has been formed from a multitude of individual patterns ( 120 ) formed from coating lines ( 114 ). 
     
     
         12 . The cleaning article ( 100 ) of  claim 11 , wherein at least one individual pattern ( 120 ) takes the form of a group of patterns ( 124 ) comprising at least two pattern elements ( 126 ) formed from coating lines ( 114 ). 
     
     
         13 . The cleaning article ( 100 ) of  claim 12 , wherein a first pattern element ( 126 ) encircles at least regions of a second pattern element ( 126 ) or further pattern elements ( 126 ), and/or in that a first pattern element ( 126 ) is assigned to and arranged in contact with a second pattern element ( 126 ) or further pattern elements ( 126 ) alongside one another. 
     
     
         14 . The cleaning article ( 100 ) of  claim 1  wherein the first side face ( 102 ) has a degree of coverage by the coating ( 112 ) of at least 6% and at most 50%. 
     
     
         15 . The cleaning article ( 100 ) of  claim 1  wherein the coating lines ( 114 ) take the form of continuous lines and/or lines that are interrupted at least in regions where the interruption is not longer than 10 times the line width of the line adjacent to this site of interruption. 
     
     
         16 . The cleaning article ( 100 ) of claim,  1  wherein the coating ( 112 ) is polymer-based and formed from materials having a Shore A hardness of at least 30 and of at most 95.
