Description
Die erfindungsgemäßen analytischen Elemente können selbsttragende Elemente sein oder aber einen Schichtträger aufweisen. Als Schlchtträgermaterlallen eignen sich üblich« bekannte Schlchtträgermateilallen aus Polymeren, beispielsweise Celluloseacetat, Poly(äthylenterephthalat), Polycarbonate und Polyvlnylvertlndungen, wie !beispielsweise Polystyrole.
Zur Herstellung der Schicht wurde eine Beschichtungsmasse verwendet, die bestand aus:
10,6 g
15 Tropfen
2,16 g/m2
Die erhaltene Dispersion wurde dann zu einer Beschichtungsmasse aus:
Wasser mit 10 Gew.-% Gelatine)
Polyurethanelastomer 1,5
