  • Water-absorbing resin particles, absorber comprising same, and absorbent article
    Patent number: 10174174
    Abstract: Provided are the following: water-absorbing resin particles with which an absorber can be manufactured, the absorber enabling ample anchoring to be obtained without compromising on water absorbency; and an absorber obtained by anchoring together the water-absorbing resin particles and a fibrous base material. The present invention is: core-shell water-absorbing resin particles constituted of a core layer (P) containing a water-absorbing resin (A) and a shell layer (Q), the shell layer (Q) containing a thermoplastic resin (B) having a melting point of 50 to 180° C., and the thermoplastic resin (B) being a polymer having a hydrophobic block comprising a polyolefin; an absorber obtained by anchoring the water-absorbing resin particles to a fibrous base material (F); and an absorbent article made using such absorber.
