Abstract
An aqueous gel that is prepared by gelling a polymer components, the polymer components containing polymer A, which is obtained by polymerizing a monomer component containing a betaine monomer represented by the formula (I): wherein Rrepresents hydrogen atom or an alkyl group, Rrepresents an alkylene, arylene, aralkylene, —COOH— or —CONH— group; Rand Rrepresent an alkyl group, and Rrepresents an alkylene group, and a polymer B, which is obtained by polymerizing a monomer component containing an acidic monomer represented by the formula (II): wherein Rrepresents hydrogen atom or an alkyl group; Rrepresents 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.
