Photocurable compositions include a photopolymerisable binder comprising a water reducible multi-functional polyurethane acrylate oligomer, a multi-functional acrylate monomer, water, and a vinyl ether monomer, and a free radical photoinitiator. They show properties exhibited by similar compositions containing N-vinyl-2-pyrrolidone without containing it, and can be used to produce prints on paper and paper related products without the release of harmful solvents or monomers. The composition may be in the form of a varnish or lacquer, or may include a colorant and be in the form of an ink, e.g. for screen printing. |
