<p>An aqueous gel that is prepared by gelling polymer components, said polymer components comprising polymer A, which is obtained by polymerizing a monomer component containing a betaine monomer represented by formula (I) [wherein: R1 represents a hydrogen atom or an alkyl group; R2 represents an alkylene, arylene, aralkylene, -COO- or -CONH- group; R3 and R4 represent an alkyl group; and R5 represents an alkylene group], and polymer (B), which is obtained by polymerizing a monomer component containing an acidic monomer represented by formula (II) [wherein: R1 represents a hydrogen atom or an alkyl group; and R6 represents an optionally neutralized sulfonate group, an optionally neutralized phosphate group, or an alkyl, aryl, aralkyl, carboxyl or amino group carrying an optionally neutralized sulfonate group or an optionally neutralized phosphate group].</p> |
