  • Radiation curable aqueous compositions for low extractable film packaging
    Publication number: 20040180226
    Abstract: A method for producing a low-extractable film which complies with governmental requirements for direct contact with food, medicine and cosmetics, from an actinic radiation curable homogeneous aqueous composition containing a water soluble compound having at least one &agr;,&bgr;-ethylenically unsaturated, radiation polymerizable group and water carried out by applying the homogeneous aqueous composition to a surface then irradiating the surface with actinic radiation in the presence of the water. Low extractable films, packaging materials and printing inks made from same are also disclosed.
