| titleOfInvention | Particulate water absorbing agent including polyacrylic acid (polyacrylate) based water absorbing resin as a principal component, method for production thereof, water-absorbent core and absorbing article in which the particulate water absorbing agent is used |
| abstract | As a characteristic that had not been known conventionally at all, 'permeability potential under pressure (PPUP)' of a particulate water absorbing agent is regulated, and further, 'range of particle size distribution' and 'coloring' are concomitantly regulated. The present invention is directed to a particulate water absorbing agent having the following (a) to (c): (a) permeability potential under pressure (PPUP) being 50 to 100%; (b) yellowness index (YI) being 0 to 10, and rate of change of yellowness index (ΔYI) being 100 to 150% following a coloring acceleration test for 14 days at 70 ± 1°C and the relative humidity of 95 ± 1%; and (c) particles of smaller than 150 µm specified by standard sieve classification accounting for 0 to 5% by weight, weight average particle diameter (D50) being 200 to 550 µm, and logarithmic standard deviation (σζ) of particle size distribution being 0.20 to 0.40. |
