A water-developable photo-polymerizable composition is disclosed, together with a printing plate prepared therefrom. The photo-polymerizable composition comprises a copolymer of an alpha , beta -ethylenically-unsaturated carboxylic acid and a vinyl monomer, a vinyl compound having a secondary or tertiary nitrogen atom, an ethylenically-unsaturated monomeric compound, and a photosensibilizer. Printing plates prepared from the composition are water-developable and also water-resistant following developing. |
