Abstract: The present invention relates to particulate, linear, sheet-like, or three-dimensional structures which comprise, at least on their surface, a hydrophilicizing amount of at least one polymer which has urethane groups and/or urea groups, and also ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.
