摘要:
A particulate water absorbing agent of the present invention is a water absorbing agent containing a water absorbing resin as a main component, the particulate water absorbing agent containing a polyvalent metal cation and satisfying: (1) the polyvalent metal cation is contained in an amount between 0.001 wt% and 5 wt% relative to the amount of the water absorbing agent (2) an absorbency without pressure (CRC) is not less than 28 (g/g) and an absorbency against pressure (AAP 4.83 kPa) is not less than 10 (g/g) (3) the absorbency against pressure and the absorbency without pressure satisfy 77 ≤ AAP (4.83 kPa) + 1.8 × CRC ≤ 100 and (4) a moisture content of the water absorbing agent is between 5 wt% and 20 wt%. This provides a water absorbing agent which has blocking resistance after moisture absorption, is excellent in stability to shock and suppresses Re-Wet when used in a diaper.
