PURPOSE: Provided is an absorption material for use in an absorbent article such as a diaper, an incontinence protector, a sanitary napkin or the like. CONSTITUTION: An absorption material (50; 60) comprises a carrier material exhibiting a coating (51; 61) of a thermosensitive polymer with a cloud point at a temperature in the vicinity of and somewhat below the body temperature of a healthy human being. The absorption properties of the polymer change at the cloud point, so that the polymer substantially lacks absorption capacity at a first temperature on one side of the cloud point but exhibits good absorption properties at a second temperature on the other side of the cloud point. Furthermore, the invention includes an absorbent article such as a diaper, an incontinence protector, a sanitary napkin, or the like, having an absorption body comprising an absorption material coated with a thermosensitive polymer.
