Abstract: Disclosed are porous resin particles which contain a polymer of a monomer mixture containing, as monomers, at least a monofunctional (meth)acrylic acid ester and a crosslinking monomer. The monofunctional (meth)acrylic acid ester accounts for 1 wt % to 50 wt % of the monomer mixture, and the crosslinking monomer accounts for 50 wt % to 99 wt % of the monomer mixture. The porous resin particles have a specific surface area of 190 m2/g to 300 m2/g and a bulk specific gravity of 0.25 g/mL to 0.45 g/mL.

Abstract: A hydrogel has water, a polyvinylsulfonic acid-based polymer, and a polymer matrix containing the water and the polyvinylsulfonic acid-based polymer, in which the polymer matrix contains a copolymer of a monofunctional monomer having one ethylenically unsaturated group and a polyfunctional monomer having 2 to 6 ethylenically unsaturated groups, the copolymer has a hydrophilic group binding to its main chain, the polymer matrix is contained in an amount of 2 to 80 parts by mass in 100 parts by mass of the hydrogel, a polymer derived from the polyfunctional monomer is contained in a proportion of 0.1 to 5 parts by mass in 100 parts by mass of the copolymer, the polyvinylsulfonic acid-based polymer is contained in an amount of 0.1 to 150 parts by mass in 100 parts by mass of the polymer matrix, and the polyvinylsulfonic acid-based polymer has a weight average molecular weight of 200,000 to 3,000,000.
