Images are prepared by a process in which a layer, supported on a substrate, of a liquid composition comprising (a) an anaerobically polymerizable material and (b) a photopolymerizable material is maintained in a substantially oxygen-free environment such that the composition solidifies. It is then exposed imagewise to actinic radiation and treated with a developer to remove parts of the layer which have not been struck by the radiation. The anaerobically polymerizable and photopolymerizable materials may be a mixture of two or more materials having these different functions, such as an acrylate ester with an azido compound, or the two functions may be combined in a single molecule. The products are suitable for use in producing printing plates and printed circuits.
图像是通过一种过程准备的,该过程在基底上支撑一层液态组合物(a)厌氧聚合材料和(b)光聚合材料,使其保持在基本无氧的环境中,使组合物凝固。然后,它被图像方式暴露于光致辐射并用显影剂处理,以去除未被辐射击中的层的部分。厌氧聚合和光聚合材料可以是具有这些不同功能的两种或更多种材料的混合物,例如丙烯酸酯和偶氮化合物,或这两种功能可以结合在单个分子中。这些产品适用于生产印刷版和印刷电路。
