The present invention provides an imaging element comprising on a hydrophilic base a hydrophobic photopolymerizable composition capable of being irradiated with actinic light through the support and/or through the front and containing a photopolymerizable composition characterized in that a water-swellable barrier layer comprising at least one non-proteinic water-soluble film-forming polymer is located between said hydrophilic base and said hydrophobic photopolymerizable composition, contiguous to the hydrophilic base and is coated at a ratio of 0.01 to 2.0 g/m2, said water-swellable barrier layer being capable of being peeled off of said hydrophilic base by dry development.
