The invention relates to paper and method for manufacturing paper suitable for use as a layer of a release liner, the paper having density equal to or less than 1200 kg/m^(3), the paper having a ratio of grammage to thickness of the paper in micrometres equal to or higher than 1.0, wherein the grammage refers to the weight of the paper in grams per square meter, the paper comprising cellulose fibres from- bleached chemical pulp and- bleached chemithermomechanical pulp,wherein the bleached chemithermomechanical pulp comprises cellulose fibres from hardwood and softwood.


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.
