摘要:
A process and article for a retroreflective polymeric coated flexible fabric material having a retroreflective layer and a polymeric compatibilizing layer welded to a polymeric coated outer surface of a flexible fabric material. The compatibilizing layer provides an intermediate layer between the retroreflective layer and the flexible fabric material creating suitable bond strength between dissimilar polymers.
摘要:
The present invention relates to an illumination device (20) comprising a light source (4). and at least one light transmissive film (2) arranged above said light source (4) so that at least part of the light emerging from the light source (4) is transmitted through said film (2), wherein said film (2) has a first major surface facing the light source (4) and a second major surface arranged opposite to said first surface, said light-transmissive film (2) being diffusive for transmitted light incident from the light source (4) on the first major surface and retroreflective for light incident on said second major surface.
