ABSTRACT:
An integral multilayer analytical element comprising a reagent layer containing an indicator reagent composition capable of producing a detectable change corresponding to an analyte and a porous spreading layer composed of a fibrous fabric superposed on the reagent layer, wherein the yarn of said fabric comprises fibers having roughed surface, and an integral multilayer analytical element comprising a water-absorptive layer containing a hydrophilic polymer and a porous spreading layer composed of a fibrous fabric containing an indicator reagent composition capable of producing a detectable change corresponding to an analyte superposed on the water-absorptive layer, wherein the yarn of said fabric comprises fibers having roughed surface.
The rouging is carried out, for example, by alkali etching.
