ABSTRACT:
A process for improving the adhesion of polymeric substances containing organic groups or composed of such groups to the surfaces of alkaline earth metal carbonates, which comprises applying an organic aprotic solvent solution containing at least one organosilicon compound having fluorine bonded directly to silicon and an average of not more than 1.8 SiC-bonded organic radicals per silicon atom to the surface of alkaline earth metal carbonates and removing the solvent before a polymeric substance containing organic groups is applied to the pretreated alkaline earth metal carbonate surface.
