An absorbent structure comprising a water-absorbing material containing coated water-absorbing polymer particles, the absorbent structure being suitable for absorption and retention of bodily fluids, and being produced by a process comprising the steps of: a) coating water-absorbing polymer particles with an aqueous composition comprising a film-forming polyurethane and pyrogenic silica in a weight ratio from about 1:1 to about 1:4; andb) heat-treating the coated particles at above 50° C. 2. An absorbent structure as in claim 1, wherein the film-forming polyurethane and the pyrogenic silica are used in a weight ratio from about 1:1.3 to about 1:3. 3. An absorbent structure as in claim 1, wherein the film-forming polyurethane and the pyrogenic silica are used in a weight ratio from about 1:1.2 to about 1:3. 4.
