ABSTRACT:
Two absorbent layer materials for a sample liquid are connected with one another in such a way that the sample liquid can pass through from one layer into the other layer through the connecting surface between the layers a hot melt adhesive is applied to the first layer material in the form of a discontinuous coating and the second layer material is pressed on while the melt adhesive is still sufficiently hot. The amount of the melt adhesive and the pressing-on force are adjusted to one another with regard to the surface properties in such a manner that, even after the application and pressing on of the second layer material, a continuous liquid-permeable melt adhesive layer does not result. The diagnostic test carrier for the investigation of a sample liquid has two absorbent layers arranged over one another so that the sample liquid can pass through the connecting surface between the layers from one layer into the other, wherein the absorbent layers are connected with one another by a discontinuous liquid-permeable melt adhesive layer.
