摘要:
The water absorbent resin composition and the production method thereof according to the present invention are characterized by including: water absorbent resin particles having an internal cross-linked structure obtained by polymerizing a water-soluble unsaturated monomer; a nitrogenous ketone compound (A) (containing no carboxyl group) having a structure represented by formula (1); and a bivalent and/or trivalent and/or tetravalent water-soluble metal salt, wherein a total amount of the nitrogenous ketone compound (A) and the bivalent and/or trivalent and/or tetravalent water-soluble metal salt ranges from 0.01 to 100 parts by mass with respect to 100 parts by mass of the water absorbent resin particles, thereby providing a water absorbent resin composition, having an excellent absorption capacity represented by a centrifuge retention capacity (CRC), an absorbency against pressure of 4.83 kPa (AAP) etc., having excellent liquid permeability and liquid diffusion properties, having excellent fluidity at the time of moisture absorption, having an excellent damage resistance property, effectively suppressing occurrence of dusts, hardly bringing about permeation of added metal compounds into water absorbent resin particles, hardly bringing about segregation of added metal compounds.
