Abstract: Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.
Abstract translation: 具有双面结构的薄膜制品是其中两个主要表面具有结构化表面的薄膜制品。 结构化薄膜制品具有第一主表面和第二主表面，其中每个表面具有形成重复图案的多个间隔开的突起。 每个重复图案具有长轴，其中长轴是重复图案的平移方向上的主轴之一。 第二主表面上的重复图案的长轴与第一主表面上的长轴形成倾斜角，其中角度在重复图案的旋转对称角的10-90％的范围内。 结构化膜是单一基底。 通过提供具有两个主表面并同时使主表面与第一微结构工具和第二微结构工具接触的可流动材料组合物来制备结构化薄膜制品。 每个微结构工具具有包括多个凹陷的图案的结构化表面。

Abstract: Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.
