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.
