A photopolymerizable composition and photosensitive elements produced therefrom are disclosed which include a monomer component, a polymer component and a polymerization initiator activatable by actinic light. The monomer component includes at least one water soluble monofunctional unsaturated ethylenic monomer, and at least one polyfunctional unsaturated ethylenic monomer. The polymer component includes a partially saponified, water-soluble, polyvinyl acetate which is compatible with said monomer components. The ratio, by weight, of polyfunctional monomer to monofunctional monomer is in the range of about 0.2 to about 0.6, and the ratio, by weight, of said monomer component to said polymer component is in the range of about 0.7 to about 1.2.
