DRYING PROCESS ANALYSIS ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a drying process analysis element without any irregularity in the concentration and irregularity in color development of a reagent that is contained by applying the reagent from a polyester cloth development layer. SOLUTION: In the dry process analysis element, at least one water transmission layer is laminated on a water-transmitting transparent support, and further the development layer that is made of polyester and has a function for uniformly developing liquid is laminated. Solution is made by the drying process analysis element featuring that the surface of fiber for composing the polyester development layer is covered with an organic solvent.
