Essential for good processing properties of the hot melt adhesive are high compatibility of tackifier and base polymer. To produce bright and easily processable hot-melt adhesives, it is important that the at least partially hydrogenated hydrocarbon resins used for this purpose are as free as possible from unwanted by-products. These can lead to dark discolorations in the hydrocarbon resin and incompatibilities with other components of a hot-melt adhesive.
