         11 . The abrasive article of  claim 1 , and further comprising a laminate coated directly to the first major surface of the backing, and wherein the make layer is bonded to the laminate. 
     
     
         12 . The abrasive article of  claim 1 , wherein the backing is pretreated with a backsize, a presize, or a saturant. 
     
     
         13 - 16 . (canceled) 
     
     
         17 . The abrasive article of  claim 1 , wherein the patterned coating comprises a repeating unit. 
     
     
         18 . The abrasive article of  claim 1 , wherein the patterned coating extends from a center of the abrasive article to an edge of the abrasive article. 
     
     
         19 . (canceled) 
     
     
         20 . A method of making a coated abrasive article, the method comprising sequentially:
 depositing a curable make layer precursor on a major surface of a backing;   depositing a plurality of abrasive particles onto the curable make layer precursor;   at least partially curing the curable make layer precursor;   depositing a curable size layer precursor on the plurality of abrasive particles; and   at least partially curing the curable size layer precursor; and   wherein one of the curable make layer precursor and the curable size layer are deposited in a pattern on the major surface of the backing.   
     
     
         21 . The method of  claim 20 , wherein the pattern comprises a repeating unit. 
     
     
         22 . (canceled) 
     
     
         23 . The method of  claim 20 , wherein the pattern comprises a first color and a second color. 
     
     
         24 . The method of  claim 23 , wherein the first color is a color of a cured size layer. 
     
     
         25 . The method of  claim 23 , wherein the method also comprises depositing a supersize layer and, wherein the supersize layer is deposited in a supersize pattern, and wherein the second color comprises a supersize color. 
     
     
         26 . (canceled) 
     
     
         27 . The method of  claim 20 , wherein the plurality of abrasive particles are deposited such that only a first portion of each abrasive particle embeds within the curable make layer precursor, and a second portion of each abrasive particle is free of make layer precursor. 
     
     
         28 . (canceled) 
     
     
         29 . The method of  claim 20 , and further comprising depositing a laminate coated directly to the first major surface of the backing, and wherein the make layer bonds to the laminate. 
     
     
         30 . (canceled)
