Abstract

A composite laminar material (11) suitable for use in the production of a release liner. This comprises a substrate (12) of at least partly porous material, a barrier layer (13), on at least one surface of the substrate (12), of substantially impermeable material having a smooth surface facing away from the substrate, the said material of the barrier layer (13) being one to which a layer of low-adhesion material such as silicone will bond if applied thereto. A method of producing such a composite laminar material (11) involves applying a barrier layer (13) of substantially impermeable material in thixotropic form or as part of a thixotropic composition to at least one face of a web (12) of woven or non-woven fibrous material in such a way as to lie on the surface of the web (12) without substantial penetration, the barrier layer (13) being cured by irradiation with ultraviolet light to form a smooth surface, and subsequently applying a layer (14) of release agent to the barrier layer (13) to form a substantially continuous layer over at least a part of the area.
