water absorbing agent and its processes of production and use. The present invention provides a water absorbing agent having excellent urine resistance, a water absorbing agent which has no not only excellent resistance to urine, but also excellent absorption properties that are stable to any urine composition and show little change over time, and the production process and uses for these water absorbing agents. Specific or greater value of absorbability under a charge in a process wherein the absorbability under a charge is measured in a new way using a specific liquid to be absorbed, and the present invention provides an absorbent matter and an absorbent article which demonstrate a specific or greater value of the new absorption index such as, for example, taken from the absorption capacity under a load or from the concentration resin traction using the above water absorbing agent. The present invention further provides a production process for a water absorbing agent having the specific parameter above. |
