    • An exposed lens retroreflective article (100), transfer articles comprising same, and methods of making same. The retroreflective article can include a binder layer (114); a layer of transparent microspheres (108) partially embedded in the binder layer; and reflective layer (110) disposed between the binder layer and the microspheres. The reflective layer (110) can include a dielectric mirror, which can include a first stack (115) and a second stack (111) positioned in planar contact with the first stack, wherein each of the first stack and the second stack comprises at least one bilayer (119), wherein each bilayer comprises a first material with a first bonding group and a second material with a complementary second bonding group. The transfer article can include the retroreflective article and a carrier web. The method can include partially embedding transparent microspheres in a carrier web; applying the reflective layer to the microspheres, and applying a binder layer composition to the reflective layer.
    • 一种暴露的透镜逆向反射制品(100),包括其的转移制品及其制造方法。 逆向反射制品可以包括粘合剂层(114); 一层部分嵌入粘合剂层中的透明微球体(108); 和布置在粘合剂层和微球体之间的反射层(110)。 反射层(110)可以包括电介质镜,该电介质镜可以包括定位成与第一叠层平面接触的第一叠层(115)和第二叠层(111),其中第一叠层和第二叠层中的每一个至少包括 一个双层(119),其中每个双层包括具有第一结合组的第一材料和具有互补的第二结合组的第二材料。 转印物品可以包括逆向反射制品和载体网。 该方法可以包括将透明微球体部分嵌入载体网状物中; 将反射层施加到微球体,并将粘合剂层组合物施加到反射层。
