摘要： An optical construction includes a reflective polarizer layer having a first pass axis and an absorptive polarizer layer having a second pass axis that is substantially aligned with the first pass axis. At least one electrically conductive light scattering layer is arranged between the reflective polarizer layer and the absorptive polarizer layer.

摘要： Provided herein are acoustic articles (100) that include a porous layer (102) and heterogeneous filler (104) received in the porous layer. The heterogeneous filler is substantially non-porous and present in an amount of from 0.25% to 7% by volume relative to the total volume of the porous layer and has a specific surface area of from 0.01 m2/g to 1 m2/g. The acoustic article has a flow resistance of from 500 MKS Rayls to 12,000 MKS Rayls.
