Abstract

The invention relates to an adsorptive filtering material with biological and chemical protective function, in particular with protective function with regard to both chemical and biological poisons and noxiants, such as chemical and biological warfare agents, the adsorptive filtering material having a multilayered construction comprising a first outer supporting layer and a second outer supporting layer and an adsorptive layer disposed between the two supporting layers, the adsorptive filtering material further comprising at least one catalytically active component, the first outer supporting layer and/or the second outer supporting layer being provided with the catalytically active component. The adsorptive filtering material is particularly useful in NBC protective materials (for example NBC protective apparel) and also for production of filters.
