Water-absorbing agent and its production process and use |
摘要 |
The present invention provides: a water-absorbing agent which has high absorption capacity, fast absorption speed, and excellent liquid permeability; and a production process and a use for such a water-absorbing agent. A water-absorbent fine particle having a lower absorption capacity than a water-absorbent resin particle is fixed to the surface of the water-absorbent resin particle, or portions having a higher crosslinking density than internal portions are discontinuously present in the neighborhood of the surface of the water-absorbent resin particle. In addition, the water-absorbing agent is produced using a water-absorbent crosslinking agent which is swellable in itself.
