A process for producing a radiation crosslinked printing medium comprises: (a) coating a substrate with a coating composition comprising: (1) volatile aqueous solvent; (2) binder dissolved in the volatile aqueous solvent; (b) exposing the coated substrate to ionizing radiation to form a crosslinked coating; and (c) removing volatile aqueous solvent from the crosslinked coating. Preferably the binder comprises water-soluble poly(ethylene oxide) having no ethylenically unsaturated terminal groups, water-soluble poly(ethylene oxide) having at least some ethylenically unsaturated terminal groups, water-soluble poly(vinyl alcohol), water-soluble poly(vinylpyrrolidone), or a mixture of two or more thereof. |
