摘要： Disclosed are water-absorbent resin particles having a gel outflow test force measured by the following method of 5 to 14 N. The measuring method for gel outflow test force includes: producing a swollen gel by allowing the water-absorbent resin particles to absorb 29 times as amount of physiological saline as the water-absorbent resin particles under stirring; evenly putting 20 g of the swollen gel in a cylinder with an inner diameter of 5 cm and having a hole with a diameter of 5 mm at a bottom part, compressing the swollen gel in the cylinder at a rate of 10 mm/min with a jig with a diameter of 4.9 cm, thereby recording a test force at a time point when a part of the swollen gel flows out from the hole at the bottom part of the cylinder, as the gel outflow test force.

摘要： Provided is a viscous composition that comprises a carboxyl-group-containing water-soluble copolymer, the composition having excellent viscosity even when an amino acid-based surfactant is contained in an amount greater than that of betaine. More specifically, provided is a viscous composition comprising (A) a copolymer obtained by polymerizing at least 100 parts by mass of a (meth)acrylic acid and 0.5 to 5 parts by mass of a (meth)acrylic acid alkyl ester having an alkyl group with 10 to 30 carbon atoms, (B) an amino acid-based surfactant, (C) a betaine, (D) an alkyl glycoside, and (E) an organic acid salt, wherein the mass content of (B) is equal to or greater than the mass content of (C).

摘要： Disclosed is a method for evaluating liquid leakage properties of water-absorbing resin particles. The method includes, in the following order: disposing a water-absorbing layer formed from the water-absorbing resin particles along an inclined plane inclined with respect to a horizontal plane; injecting a test solution which is in the form of liquid droplets and contains water into the water-absorbing layer exposed; and measuring a diffusion distance which is a distance in which the test solution injected into the water-absorbing layer diffuses along the inclined plane in a predetermined time. An angle of inclination formed by the horizontal plane and the inclined plane is 25 degrees or larger and 40 degrees or smaller.

摘要： Water-absorbing resin particles are disposed, the water-absorbing resin particles including: a polymer particle containing a crosslinked polymer having a monomer unit derived from an ethylenically unsaturated monomer including at least one kind of compound selected from the group consisting of (meth)acrylic acid and a salt thereof; and a plurality of inorganic particles disposed on a surface of the polymer particle, in which a proportion of a (meth)acrylic acid and a salt thereof is 70 to 100 mol% with respect to a total amount of monomer units in the crosslinked polymer. In a case where a water absorption speed index I = (value of non-pressurization DW after 10 seconds) × 6 [mL/g], and a water absorption speed index II = (value of non-pressurization DW after 3 minutes)/3 [mL/g], a static suction index α calculated by the following formula: α = I + II / 2 is 5.0 mL/g or higher.
