Abstract:
The present invention relates to an absorbent structure suitable in, or being an adult or infant diaper or feminine hygiene article, comprising a water-absorbing material comprising water-absorbing particles that comprise a film coating, comprising an elastic film-forming polymer and a coalescing agent.The invention also relates to an absorbent structure comprising a water absorbent material obtainable by a process of: a) spray-coating water-absorbing polymeric particles with an elastic film-forming polymer in a fluidized bed reactor at a temperature in the range from 0° C. to 150° C. and b) heat-treatment of the coated polymeric particles at a temperature above 50° C., wherein in step a) and/or b) a coalescing agent is added.
