Patent ID: 7981833

Claim:
An aqueous-liquid-absorbing agent, which is an aqueous-liquid-absorbing agent comprising water-absorbent resin particles as essential components, wherein the water-absorbent resin particles are obtained by a process including the steps of polymerizing a water-soluble ethylenically unsaturated monomer including acrylic acid and/or its salt in an amount of 50 to 100 mol % and have a crosslinked structure in their inside; with the aqueous-liquid-absorbing agent exhibiting an absorption rate (FSR) of not less than 0.2 g/g/s, a water absorption capacity (CRC) of 10 to 20 g/g, a saline flow conductivity (SFC) of not less than 400×10 −7 cm 3 ·s/g, and a wet porosity of not less than 20% Furthermore, said aqueous-liquid-absorbing agent is a particulate shape and of which not less than 90 weight % is in the form of particles having particle diameters in the range of 150 to 600 μm.
