摘要

A photopolymerizable recording material is diclosed comprising a base material, a photopolymerizable layer and a cover layer which comprises a water-soluble polymer which is substantially impermeable to atmospheric oxygen, and a polymer which binds atmospheric oxygen and is virtually completely soluble in water at 20° C. The material displays reduced sensitivity to atmospheric oxygen, even on prolonged storage and at elevated ambient temperatures and elevated atmospheric humidity.
