摘要：
The present invention provides a water-absorbent resin composition which contains an aminoacetic chelating agent and is excellent in the urine resistance, wherein the water-absorbent resin composition is excellent further in the light resistance and becomes little colored and might have deodorizability. A water-absorbent resin composition, which comprises a water-absorbent resin and an aminoacetic chelating agent, wherein the mixing ratio of the aminoacetic chelating agent in the water-absorbent resin composition is not less than 10 ppm of the water-absorbent resin, and wherein the total content of nitrilotriacetic acid and its salt in the water-absorbent resin composition is not more than 1 ppm of the water-absorbent resin composition.
