Overcoat for light-sensitive materials comprising (1-vinylimidazole) polymer or copolymer

摘要

The invention relates to water-soluble layers which in addition to polyvinyl alcohol comprise poly(1-vinylimidazole) or a copolymer of 1-vinylimidazole and at least one further monomer as a further component. These layers can be used as an overcoat on the light-sensitive layer of printing plates.
