MICROSTRUCTURED ARTICLES COMPRISING NITROGEN CONTAINING INGREDIENT |
摘要 |
<p>Microstructured articles, such as a retroreflective articles, having a plurality of (e.g. cube-corner) microstructured elements projecting from a major surface are described. The microstructured (e.g.) cube-corner elements or interface with an adjacent layer comprises certain nitrogen-containing ingredients. The inclusion of such nitrogen-containing ingredients can improve the adhesion of the (e.g. cube-corner) elements to adjacent (e.g. olefinic) layers such as a body layer, seal film layer, or combination thereof. The flexible retroreflective articles have a light transmissive polymeric body layer having an elastic modulus of less than 7×108 pascals.</p> |
