    摘要: A water-absorbent sheet composition comprising a structure in which a water-absorbent resin and a hot melt adhesive are sandwiched with two or more sheets of hydrophilic nonwoven fabrics, wherein the hydrophilic nonwoven fabrics have a basis weight of 30 g/m 2 or more, and wherein the water-absorbent resin is contained in an amount of from 10 to 150 g/m 2 , and wherein the hot melt adhesive is contained in an amount of from 0.10 to 1.0 time that of the amount of the water-absorbent resin contained (based on weight). The water-absorbent sheet composition of the present invention exhibits some excellent effects that the sheet composition has sufficient absorbency not only for a liquid having a low viscosity but also a liquid having a high viscosity, without undergoing deformation of shape before or after liquid absorption, while being thin in style. Therefore, the water-absorbent sheet composition of the present invention is used as an absorbent material for sanitary napkins and incontinence pads, whereby a hygienic material not only that is thin and has excellent external design, but also free from inconveniences such as liquid leakage can be provided.
