ABSTRACT:
A release base paper having silicate-containing primer coats based on potassium or sodium waterglass, due to which the penetration of subsequent coatings comprising aqueous, solvent-containing or solvent-free silicone systems into the texture of the paper is decreased and a reduction in the silicone requirement in order to achieve predetermined release forces is thereby achieved.
