The fibrous nonwoven layer is coated over a coated area on the wearer facing side of the topsheet with a coating composition. The coating composition comprises a lubricant agent comprising an alkoxylated diester selected from the group consisting of fatty ester lubricants.

Claims (20)

wherein the fibrous nonwoven layer is coated over a coated area on the wearer facing side of the topsheet with a coating composition, the coating composition comprises a lubricant agent comprising an alkoxylated diester of myristyl alcohol and adipic acid,

wherein the coating composition comprises one or more surfactants, and

wherein the composition comprises from 50% by weight to 95% by weight of the lubricant agent and from 5% by weight to 50% by weight of the one or more surfactants.

2 . The absorbent article according to claim 1 , wherein the fibrous nonwoven layer consists essentially of thermoplastic fibers.

3 . The absorbent article according to claim 1 , wherein the lubricant has an HLB which is within the range of from 6 to 18.
