RETROREFLECTIVE ARTICLE HAVING A COLORED LAYER CONTAINING REFLECTIVE FLAKES AND A DYE COVALENTLY BONDED TO A POLYMER

摘要

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 refletive flakes (16) a nd 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.
