Abstract: A multilayer optical film has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film. Heating element(s) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered region(s) of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered region(s) to pattern the film. The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered region(s), while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered region(s).

Abstract: A multilayer optical film (130) has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film Heating elements (122) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered regions of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered regions to pattern the film The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered regions, while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered regions.
Abstract translation: 多层光学膜（130）具有通过结构性或相消干涉选择性地反射光以提供第一反射特性的微层的分组。 至少一些微层是双折射的。 稳定层附近并覆盖薄膜的外部暴露表面附近的微层分组物，加热元件（122）可以物理接触薄膜，以通过热传导在薄膜的改变区域将散热的热量传递给分组， 第一反射特性改变为改变的区域中改变的反射特性以对膜进行图案化。稳定层提供足够的热传导以允许来自加热元件的热量改变（例如，减少）设置在外部暴露的附近的双折射微层的双折射 同时提供足够的机械支撑以避免在改变的区域中的外暴露表面附近的微层的实质层变形。
