Retroreflective article having coloured layer containing reflective flakes and dye convalently bonded polymer

一种露出透镜的逆向反射制品(10)，它包括：着色层(14)和部分嵌入着色层(14)的光学元件(12)，着色层(14)包括反射薄片(16)和与聚合物(18)共价键相连的染料。经多次工业洗涤循环后该制品能保持其颜色。在着色层制造过程中使用活性染料、反射薄片和/或聚合物前体能制得具有洗涤耐久性的着色的逆向反射制品而无需使用溶剂和临时载体。 Exposed lens retroreflective article 10 that comprises a colored layer 14 and a layer of optical elements 12 that are partially embe...

Summary:一种露出透镜的逆向反射制品(10)，它包括：着色层(14)和部分嵌入着色层(14)的光学元件(12)，着色层(14)包括反射薄片(16)和与聚合物(18)共价键相连的染料。经多次工业洗涤循环后该制品能保持其颜色。在着色层制造过程中使用活性染料、反射薄片和/或聚合物前体能制得具有洗涤耐久性的着色的逆向反射制品而无需使用溶剂和临时载体。 Exposed lens retroreflective article 10 that comprises a colored layer 14 and a layer of optical elements 12 that are partially embedded in the colored layer 14. The colored layer 14 comprises reflective flakes 16 and a dye that is covalently bonded to a polymer 18. The articles can retain their color after multiple industrial wash cycles. The use of a reactive dye, reflective flakes, and/or polymer precursor during the preparation of the colored layer enables a launderably-durable colored retroreflective article to be made without the use of a solvent and without the use of a temporary carrier.
