Abstract (en)
[origin: EP1231322A2] A microstructured paper or paper-like material (PPLM) having self-cleaning and anti-adhesive action and peaks and depressions in the surface, the distance between the peaks being 0.04-100 micro m and the peak heights 0.04-100 micro m containing a binder with particle size 0.04-50 micro m and which is hydrophobic over its whole cross section is new. An Independent claim is included for preparation of the microstructured paper with addition of a hydrophilizing agent within the framework of a wet process for treating the PPLM fibers of particle size 0.04-50 micro m and fixing the particles on the fibers with a binder.
