1. a particulate water absorbent containing is characterized in that, described particulate water absorbent containing is a principal constituent with the polyacrylate water-absorbent resin, and no absorbent rate under pressure is more than the 28g/g, and described particulate water absorbent containing satisfies following (a)~

  • (c);

    (a) stirring water dissolvable, to become component be 15~

    60 quality %;

    (b) stirring water dissolvable becomes component to become poor (the stirring water dissolvable becomes component-leave standstill water dissolvable to become component) of component is 15~

    50 quality % with leaving standstill water dissolvable;

    (c) the diffusion absorptive index is 1.40~

    10.0g/g/min;

    Wherein, stir water dissolvable and become that subscale is shown in the normal saline solution, the stripping high molecular after under agitation 16 hours, leave standstill water dissolvable and become subscale to be shown in stripping high molecular in the normal saline solution, after leaving standstill following 16 hours.
