    摘要： This invention provided a way of modifying the surface properties of substrates such as films of plastics material. The substrate is given a very thin coating of a mixture of modifying materials and the latter is then bonded to the substrate by irradiation with ultra-violet light. A modifying material which gives the desired surface properties is present as an emulsion in a solution of a second modifier which is readily bondable to the substrate by ultraviolet light. Although the resulting bonded modifying material is so thin as to lead to negligible increase in weight, the surface properties of the substrate become those of the modifying material while its bulk properties remain the same. The invention is particularly useful for imparting hydrophilic surfaces to films of plastics material.

    摘要翻译： 本发明提供了改变诸如塑料材料的薄膜的基材的表面性质的方法。 给予基材非常薄的改性材料的混合物，然后通过紫外线照射将后者粘合到基底上。 提供所需表面性能的改性材料作为乳液存在于通过紫外光容易地粘合到基底上的第二改性剂的溶液中。 尽管所得到的粘结改性材料如此薄以至于导致重量增加可忽略不计，但是基材的表面性能变为改性材料的表面性质，而其本体特性保持相同。 本发明特别可用于将亲水表面赋予塑料材料的薄膜。
