    Abstract: A printed packaging material and a method for making the same is described. On a primary surface of a thermoplastic flexible packaging material is disposed a printed image. That image includes two primary components. The first is at least one marking containing a pigment. The second is a pigment-free coating which overlies the outermost marking. The coating is made from materials which can polymerize and/or crosslink when exposed to ionizing radiation. After the film is exposed to such radiation, the coating hardens to form a protective layer over the printed markings.

    Abstract: The invention is a UV sensitive composition that undergoes a color change upon exposure to a predetermined dosage of UV-C radiation. The UV-C sensitive composition comprises a halogenated polymer, such as polyvinylidene chloride, that produces an acid upon exposure to UV radiation, and a pH sensitive dye. Upon exposure to UV-C radiation, the halogenated polymer undergoes degradation and produces HCl. The pH sensitive dye changes color as a result in an increase in HCl in the system. The composition may also include an acid scavenging composition and/or a diluent to control the amount of HCl produced in the system. The amount of HCl liberated from UV-C exposure may be selectively controlled so that a color change may be produced at a desired UV-C dosage. In some embodiments, the composition may be used to indicate a UV-C dosage from about 100 to 1600 mJ/cm2.

    Abstract translation: 本发明是在暴露于预定剂量的UV-C辐射时经历变色的UV敏感组合物。 UV-C敏感组合物包含在暴露于UV辐射时产生酸的卤代聚合物,例如聚偏二氯乙烯和pH敏感染料。 当暴露于UV-C辐射时,卤化聚合物发生降解并产生HCl。 pH敏感染料会改变颜色,导致系统中HCl的增加。 组合物还可以包括酸清除组合物和/或稀释剂以控制系统中产生的HCl的量。 可以选择性地控制从UV-C曝光释放的HCl的量,使得可以在期望的UV-C剂量下产生颜色变化。 在一些实施方案中,组合物可用于表示约100至1600mJ / cm 2的UV-C剂量。
