    摘要: Overprint compositions for toner-based prints containing at least one radiation oligomer/monomer, at least one photoinitiator, and at least one surfactant are disclosed. The overprint compositions provide a number of advantages to toner-based prints, such as, for example, those subjected to abrasives, heat, and/or sunlight since the compositions protect such images from cracking, fading, and smearing. In addition, the overprint compositions provide resistance to thermal cracking, which is assessed by image analysis of the thermal crack area after exposure of the print to thermal shock.
