    Abstract: A patterned article includes a polymeric layer having opposing first and second major surfaces and defining a plurality of through openings therein. For each through opening in at least a sub-plurality of the through openings, a metallic body is disposed in the through opening. The metallic body has a first outermost surface, an opposite second outermost surface and at least one lateral sidewall extending therebetween. The first outermost surface of the metallic body is substantially flush with the first major surface of the polymeric layer. Each lateral sidewall extends from the first outermost surface of the metallic body toward or to, but not past, the second major surface of the polymeric layer. The metallic body is substantially coextensive with the through opening in at least one cross-section parallel to the polymeric layer. The metallic bodies can be electrically isolated from one another.

    Abstract: A reflective film includes interior layers arranged to selectively reflect light by constructive or destructive interference, the layers extending from a first zone to a second zone of the film. The film has a first thickness and the interior layers provide a first reflective characteristic in the first zone; the film has a second thickness and the interior layers provide a second reflective characteristic in the second zone. The difference between the first and second reflective characteristics is not substantially attributable to any difference between the first and second thicknesses, which difference may be zero. Rather, the difference in the reflective characteristics is substantially attributable to reduced birefringence of at least some of the interior layers in one zone relative to the other zone. The film may also incorporate absorbing agents to assist in the manufacture or processing of the film. Related methods and articles are also disclosed.

    Abstract translation: 反射膜包括布置成通过结构性或相消干涉选择性地反射光的内层，所述层从膜的第一区延伸到第二区。 该膜具有第一厚度，并且内部层在第一区域中提供第一反射特性; 该膜具有第二厚度，并且内部层在第二区域中提供第二反射特性。 第一和第二反射特性之间的差异基本上不能归因于第一和第二厚度之间的任何差异，该差值可以为零。 相反，反射特性的差异基本上归因于在一个区域中的至少一些内层相对于另一区域的双折射率的降低。 该薄膜还可以包含吸收剂以协助制造或加工薄膜。 还公开了相关的方法和文章。
