Web-shaped material with an ultra-thin coating paint, which enables a durable fast spreading or a permanent, very fast transport of liquids

摘要

Web-like material (I), especially for use in diagnostic strips comprising a base material (A) with an ultrathin layer of coating varnish (B) on one or both sides which contains anionic surfactant(s) (II) based on a sulfosuccinic acid salt, where the ultrathin varnish (B) is present in amounts of 5-100 mg/m 2 after drying. An independent claim is included for a method for the production of (I) by coating a base material (A) with a coating solution containing a solvent and less than 2 (preferably less than 1) wt.% surfactant as above (II) and then drying the material to give an ultrathin layer of 5-100 mg/m 2.
