ABSTRACT:
An absorbing agent composition exhibiting excellent properties (absorbing properties), such as capabilities of maintaining high liquid diffusion and a constant absorbing capacity per unit weight, even when an amount of an absorbent resin is increased in percent by weight based on the weight of the absorbing agent composition, and an absorbent material containing such an absorbing agent composition and an absorbent product containing the absorbent material. The absorbing agent composition has a diffusing absorbency index under pressure of 1.5 g/g.multidot.min or higher with respect to a physiological saline solution under a load of 20 g/cm.sup.2. The absorbent material contains at least 40 weight percent absorbing agent composition based on the weight of the absorbent material. The absorbent product comprises an absorbent layer containing the absorbent material sandwiched by a liquid permeable sheet and a liquid impermeable sheet. The diffusing absorbency index under pressure is calculated by a device used for measuring the diffusing absorbency under pressure, that is, a weight of a physiological saline solution absorbed by the absorbing agent composition placed in a supporting cylinder for 60 minutes since the supporting cylinder is placed on a sheet with a weight is measured in time series using a balance.
