<P>PROBLEM TO BE SOLVED: To provide absorbing resin particles having a specific absorbing speed pattern, and to provide an absorbing article in which the absorbing resin particles are used, and thereby, which does not cause conventional problems of rash or the like. <P>SOLUTION: The absorbing resin particles contain: a crosslinked polymer (A1) containing, as essential constituent units, a water-soluble vinyl monomer (a1) and/or a hydrolyzable vinyl monomer (a2), and a crosslinking agent (b); and a hydrophobic substance (C). The (C) is a compound having at least one monovalent 8-26C aliphatic hydrocarbon group and at least one functional group capable of forming hydrogen bond with carboxylic group. The (C) exists inside the absorbing resin particle in an amount of 0.01-10.0 wt.%, and exists in the surface of the absorbing resin particle in an amount of 0.001-1.0 wt.%, each on the basis of the weight of the (A1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
