摘要：
The invention relates to Positive working thermal imaging assembly comprising: A) a substrate; and B) a thermally sensitive imaging element of a composite layer structure comprising: a layer on the substrate of a polymeric material soluble in aqueous alkali solution, optionally containing compounds that absorb and convert light to heat and/or a coloured dye or pigment; said first layer being converted at its surface by treatment with solutions at elevated temperatures that contain an active compound or compounds capable of rendering said first polymeric material insoluble to aqueous alkali developer at the point of contact; said layer being oleophilic; The assembly is useful as off-set lithographic printing plates, for color proofing films and photoresist. The invention also refers to the process for making such assembly and products formed therefrom.
摘要（中）：
本发明涉及正工作热成像组件，其包括：A）衬底; 和B）复合层结构的热敏成像元件，包括：基底上的可溶于碱水溶液的聚合材料的层，任选地含有吸收和转化光的化合物和/或着色染料或颜料; 所述第一层在其表面上通过在高温下用溶液处理而被转化，所述溶液含有活性化合物或能够使所述第一聚合物材料在接触点处不溶于碱性显影剂的化合物; 所述层是亲油的; 该组件可用作偏光平版印刷版，用于防色膜和光致抗蚀剂。 本发明还涉及用于制造这样的组装和由其形成的产品的方法。
