Abstract: Substrates suitable for use in a touch sensor are described. In some cases, the substrates include an inner layer and first and second heat-set polymeric outer layers. The first and second outer layers each have an in-plane birefringence of less than 0.1. The inner layer is substantially uniaxially birefringent and has an in-plane birefringence greater than 0.01. In some cases, a substrate includes a block copolymer which includes a first polyester and second polyester. The first polyester has a melting point greater than 200 ° C., and the second polyester having a melting point less than 200° C. The block copolymer includes the second polyester at 50 to 80 percent by weight. The substrate is substantially uniaxially birefringent and has an in-plane birefringence between 0.001 and 0.1.

Abstract: A tear resistant multilayer film including pluralities of first and second layers is described. The first layers include a first polymer and the second layers include a second polymer. The first polymer is polyethylene terephthalate or a first ester block copolymer that includes polyethylene terephthalate blocks at a weight percent of the first ester block copolymer of at least 50 percent and further includes glycol-modified polyethylene terephthalate blocks. The second polymer is sebacic acid-substituted polyethylene terephthalate or a second ester block copolymer that includes sebacic acid-substituted polyethylene terephthalate blocks at a weight percent of the second ester block copolymer of at least 50 percent and further includes polyethylene terephthalate blocks or glycol-modified polyethylene terephthalate blocks. The tear resistant multilayer film includes a total of 6 to 300 first and second layers.
