Zusammenfassung:Provided is a microporous material including a polyolefin matrix material; finely divided, substantially water-insoluble filler distributed throughout the matrix material, where the filler includes a positive amount of titanium dioxide; a network of interconnecting pores communicating throughout the microporous material; and optionally, a contrasting enhancing amount of a contrast enhancing material. The sum of the weight percent of the titanium dioxide and the weight percent of the optional contrast enhancing material is at least 3 weight percent based on total weight of the microporous material. Multilayer articles having a layer of the microporous material also are provided.
