AI Technical Summary
Technical Problem
Sputtering processes result in metal layers being stretched or distorted on complex surfaces, leading to visible defects and changes in aesthetic or light management characteristics.
Method used
A transfer article with a dimensionally stable but flexible substrate and a functional layer comprising ultrathin inorganic layers is used, which is microcut to form precise patterns that adapt to complex surfaces, maintaining aesthetic and light management performance.
Benefits of technology
The microcut inorganic layers provide consistent color and reflectivity, enabling articles with adjustable reflectivity and conductivity, suitable for applications like 5G touch sensors and antennas, while adapting to surface curvature.

Abstract
The present invention provides an article comprising a stack of thin inorganic layers deposited by sputter deposition on a substrate. [Solution] An article comprising: a first acrylate layer; a functional layer having a first main surface on the first acrylate layer, comprising a stack of metal layers and metal oxide layers, at least one of the metal layers comprising a cutting pattern that forms a corresponding pattern of a plurality of independent plates bounded by cutting portions, the precision-cut metal layer being about 5 nanometers to about 100 nanometers thick; a second acrylate layer on the second main surface of the functional layer; a first adhesive layer on the first acrylate layer; a first polymer film layer on the first adhesive layer; and an optically transparent second adhesive layer on the second acrylate layer and a second polymer film layer on the second adhesive layer.
