Japanese Patent JP3074265
Kind Code:
B2
Abstract:
A water absorbing agent comprising water absorbent resin particles having a particle size of 1000 mu m or less, with a two-peak mode particle size distribution, which has an inflection point in the range of 750 to 250 mu m particle size prepared by plotting the mass cumulative content percentage from the larger side of the particle size of the particle size distribution on a logarithmic normal probability paper; and an absorbent material utilizing the water absorbing agent. Since the water absorbing agent of the present invention applied in an absorbent material can realize excellent absorption rate of a liquid and planar diffusion, an absorbent material with an excellent surface dryness can be obtained even for a long time use or when the ratio of the water absorbent resin is high due to a thin shape of the product, without the risk of leakage. Accordingly, the water absorbing agent of the present invention can be preferably used in an absorbent material such as a disposable diaper.
