A RELEASE LINER COMPOSITION, A BASE MATERIAL AND A METHOD OF PRODUCING A BASE MATERIAL, AND A SURFACE TREATING AGENT FOR A BASE MATERIAL AND A USE OF A SURFACE TREATING AGENT

摘要

The invention relates to a base material for use for a release liner, to a method for producing a base material suitable for use for a release liner and a release liner comprising such base material, as well as to a use of a surface treating agent for improving the adhesion between silicone coating and a paper substrate for a release liner. By forming a surface treating agent comprising a functionalized polymer comprising functional groups comprising a vinyl group and spreading the surface treating agent on a surface of a paper substrate, a base material comprising a surface treating layer can be formed, the surface treating layer containing the vinylic group being capable of forming covalent bonding at an interface between a silicone coating and the surface treating layer, wherein the functionalized polymer comprises chains capable of remaining on the surface of the paper substrate.
