| titleOfInvention | Hydrophilic resin, absorbent article, and acrylic acid for polymerization |
| abstract | The invention provides a hydrophilic resin and an absorbent article,nboth of which display still less coloring and discoloring when preservednfor a long time. The hydrophilic resin is any one of: 1) a hydrophilicnresin, obtained by a process including the step of polymerizing anmonomer component including a major proportion of either one or bothnof acrylic acid and its salt which merely have a content of at most 0.20nppm in total of hydroquinone and benzoquinone; 2) a hydrophilic resin,ncomprising a major proportion of an acrylic polymer and a minornproportion of either one or both of hydroquinone and benzoquinone,nwith the hydrophilic resin further comprising a quinhydronationninhibitor of 10∼1,000,000 times the total weight of hydroquinone andnbenzoquinone; 3) a hydrophilic resin, comprising a major proportion ofnan acrylic polymer and merely having a coloring degree (YI) of at most 20nafter being left under conditions of the open system, 70 °C, 65% RH for 1nweek; and 4) a hydrophilic resin, which is a water-absorbent resin and isnsurface-crosslinked or surface-impregnated with a polyhydric alcohol andndisplays pH of 5.5 or less in a physiological salt solution and has annabsorption capacity of 20 g/g or more for a physiological salt solutionnunder a load of 50 g/cm 2 . In addition, the absorbent article comprises thenabove hydrophilic resin. |
