Abstract

Aryldiazosulphonates having polymerizable ethylenically unsaturated groups are excellent starting materials for water-soluble homopolymers and copolymers, which can be converted to water-soluble polymers by irradiation. Thus, the polymers can be utilized for the preparation of aqueous coating compositions.
