Abstract:
A hydrogel comprising water, a gel strength improving agent, and a polymer matrix containing the water and the gel strength improving agent, in which the polymer matrix includes 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, and the hydrogel has a breaking strength of 5 kPa or more and a breaking elongation of 200% or more in a tensile test.

Claim (Index 5):
The hydrogel according  claim 1 , comprising water, a polyvinyl alcohol-based polymer and/or a cellulose nanofiber as a gel strength improving agent, and a polymer matrix containing the water and the polyvinyl alcohol-based polymer and/or the cellulose nanofiber,\n wherein said polymer matrix includes a copolymer of a monofunctional monomer having one ethylenically unsaturated group and a polyfunctional monomer having 2 to 6 ethylenically unsaturated groups, said copolymer has a hydrophilic group binding to its main chain, said polymer matrix is contained at 1 to 30 parts by weight in 100 parts by weight of said hydrogel, a polymer derived from said polyfunctional monomer is contained at a ratio of 0.1 to 5 parts by weight in 100 parts by weight of said copolymer, when the polyvinyl alcohol-based polymer is contained as the gel strength improving agent, said polyvinyl alcohol-based polymer is contained at 10 to 150 parts by weight based on 100 parts by weight of said polymer matrix, when the cellulose nanofiber is contained as the gel strength improving agent, said cellulose nanofiber is contained at 1.0 to 50 parts by weight based on 100 parts by weight of said polymer matrix, and when water is contained in 100 parts by weight of said hydrogel so that a total content of the polymer matrix and the gel strength improving agent becomes 10 parts by weight, said hydrogel exhibits a tensile breaking strength of 10 kPa or more and a tensile breaking elongation of 100% or more.
